Abstract
A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.
Definitions Used in This Protocol
• Exclusive breastfeeding: Feeding only breast milk (at the breast or own mothers' expressed breast milk), no food or water except vitamins, minerals, and medications.
• Supplementary feedings: Additional fluids provided to a breastfed infant before 6 months (recommended duration of exclusive breastfeeding). These fluids may include donor human milk, infant formula, or other breast milk substitutes (e.g., glucose water).
• Complementary feedings: Solid or semisolid foods provided to an infant in addition to breastfeeding when breast milk alone is no longer sufficient to meet nutritional needs.
• Term infant: In this protocol “term infant” also includes early-term infants (gestational age 37–38 6/7 weeks).
Background
Given early opportunities to breastfeed, breastfeeding assistance, and instruction the vast majority of mothers and infants will successfully establish breastfeeding. Although some infants may not successfully latch and feed well during the first day (24 hours), most will successfully breastfeed with time, appropriate evaluation and support, with minimal intervention. Exclusive breastfeeding for the first 6 months is associated with the greatest protection against major health problems for both mothers and infants.1–3 Unfortunately, infant formula supplementation of healthy neonates in hospital is commonplace,4,5 despite widespread recommendations to the contrary.6–8 Early supplementation with infant formula is associated with decreased exclusive breastfeeding rates in the first 6 months and an overall shorter duration of breastfeeding.9,10 Therefore, hospitals, healthcare facilities, and community organizations that promote breastfeeding are integral in improving the exclusivity and duration of breastfeeding. 10 One way of achieving this is by following The Ten Steps to Successful Breastfeeding (the basis for the Baby-Friendly Hospital Initiative), both in the hospital and community.
Newborn physiology
Small quantities of colostrum are appropriate for the size of a newborn's stomach,11–13 prevent hypoglycemia in a healthy, term, appropriate for gestational age infant,14,15 and are easy for an infant to manage as he/she learns to coordinate sucking, swallowing, and breathing. Healthy term infants also have sufficient body water to meet their metabolic needs, even in hot climates.16–18 Fluid necessary to replace insensible fluid loss is adequately provided by breast milk alone.7,18 Newborns lose weight because of physiologic diuresis of extracellular fluid following transition from intrauterine to extrauterine life and the passage of meconium. In a prospective cohort of mothers in a U.S. Baby-Friendly designated hospital with optimal support of infant feeding, the mean weight loss of exclusively breastfed infants was 5.5%; notably, greater than 20% of healthy breastfed infants lost more than 7% of their birthweight. 19 A study of over 160,000 healthy breastfed infants resulted in the creation of hour-specific nomograms for infant weight loss for exclusively breastfed newborns that showed differentially increased weight loss in those born by cesarean section than by vaginal birth. In this study, almost 5% of vaginally born infants and >10% of those born by cesarean section had lost ≥10% of their birth weight by 48 hours after birth. By 72 hours, >25% of infants born by cesarean section had lost ≥10% of their birth weight. 20 Breastfed infants regain birth weight at an average of 8.3 days (95% confidence interval: 7.7–8.9 days) with 97.5% having regained their birth weight by 21 days. 21 Infants should be followed closely to identify those who lie outside the predicted pattern, but the majority of those breastfed infants will not require supplementation. It should also be noted that excess newborn weight loss is correlated with positive maternal intrapartum fluid balance (received through intravenous fluids) and may not be directly indicative of breastfeeding success or failure.22,23
Early management of the new breastfeeding mother
Some breastfeeding mothers question the adequacy of colostrum feedings and perceive that they have an insufficient milk supply.24,25 These women may receive conflicting advice about the need for supplementation and would benefit from reassurance, assistance with breastfeeding technique, and education about the normal physiology of breastfeeding and infant behavior. Inappropriate supplementation may undermine a mother's confidence in her ability to meet her infant's nutritional needs 26 and give inappropriate messages that may result in supplementation of breastfed infants at home. 27 Introduction of infant formula or other supplements may decrease the feeding frequency of the infant, thereby decreasing the amount of breast stimulation a mother receives, which results in a reduction of milk supply. 28
Postpartum mothers with low confidence levels are very vulnerable to external influences, such as advice to offer breastfeeding infants supplementation of glucose water or infant formula. Well-meaning healthcare professionals may recommend supplementation as a means of protecting mothers from fatigue or distress, although this can conflict with their role in promoting breastfeeding.29–31 Several sociodemographic factors are associated with formula supplementation in the hospital, and vary geographically. It is important to recognize and address these factors in a culturally sensitive manner. Inappropriate reasons for supplementation and associated risks are multiple (Appendix Table A1).
There are common clinical situations where evaluation and breastfeeding management may be necessary, but SUPPLEMENTATION IS NOT INDICATED, including:
1. The healthy, term, appropriate for gestational age infant when the infant is feeding well, urinating and stooling adequately, weight loss is in the expected range, and bilirubin levels are not of concern (depending on gestational age, time since birth, and any risk factors).
32
• Newborns are normally sleepy after an initial alert period after birth (∼2 hours). They then have variable sleep–wake cycles, with an additional one or two wakeful periods in the next 10 hours whether fed or not.
33
• Careful attention to an infant's early feeding cues, keeping the infant safely skin-to-skin with mother when she is awake, gently rousing the infant to attempt frequent breastfeeds, and teaching the mother hand expression of drops of colostrum,
34
may be more appropriate than automatic supplementation after 6, 8, 12, or even 24 hours. • Increased skin-on-skin time can encourage more frequent feeding. • Ten percent weight loss is not an automatic marker for the need for supplementation, but is an indicator for infant evaluation. 2. The infant who is fussy at night or constantly feeding for several hours
• Cluster feeding (several short feeds close together) is normal newborn behavior, but should warrant a feeding evaluation to observe the infant's behavior at the breast
35
and the comfort of the mother to ensure that the infant is latched deeply and effectively. • Some fussy infants are in pain that should be addressed. 3. The tired or sleeping mother
• Some fatigue is normal for new mothers. However, rooming out for maternal fatigue does not improve mothers' sleep time
36
and has been shown to reduce breastfeeding exclusivity.
37
Extreme fatigue should be evaluated for the safety of mother and baby to avoid falls and suffocation.
38
• Breastfeeding management that optimizes the infant feeding at the breast may make for a more satisfied infant AND allow the mother to get more rest.
The following guidelines address strategies to prevent the need for supplementation (also see Appendix 2) as well as indications for and methods of supplementation for the healthy, term (37- to 42-week), breastfed infant. Indications for supplementation in term, healthy infants are few.7,39 Table 1 lists possible indications for the administration of supplemental feeds. In each case, the medical provider must decide if the clinical benefits outweigh the potential negative consequences of such feedings.
Recommendations
Step 1. Prevent the need for supplementation
1. There is mixed, but mainly positive, evidence about the role of antenatal education and in-hospital support on the rates of exclusive breastfeeding.40–42 (I) (Quality of evidence [levels of evidence I, II-1, II-2, II-3, and III] is based on the U.S. Preventive Services 43 Task Force Appendix A Task Force Ratings and is noted in parentheses.)
2. All staff who care for postpartum women should be able to assist and assess breastfeeding infants, especially when other staff with expertise are not available.
3. Both mothers and healthcare professionals should be aware of the risks of unnecessary supplementation.
4. Healthy infants should be placed skin-to-skin with the mother, if she is awake and alert, immediately after birth to facilitate breastfeeding.7,44 (I) The delay in time between birth and initiation of the first breastfeed is a strong predictor of infant formula use and may affect future milk supply.10,45,46 (II-3, II-2, II-3)
5. It is ideal to have the mother and infant room-in 24 hours per day to respond to infant feeding cues, enhance opportunities for breastfeeding, and hence secretory activation (lactogenesis II).7,39,47,48 (III)
6. If mother–infant separation is unavoidable, milk supply is not well established, or milk transfer is inadequate, the mother needs instruction and encouragement to express her milk by hand or pump to stimulate milk production and provide expressed milk for the infant.7,39,48,49 (I, III) This process should begin within 1 hour of birth. 45 (II-2)
Step 2. Address early indicators of the possible need for supplementation
1. The infant's medical providers should be notified if the infant or mother meets any criteria for supplementation, as listed in Table 1.
2. All infants must be formally evaluated for position, latch, and milk transfer before the provision of supplemental feedings. This evaluation should be undertaken by a healthcare provider with expertise in breastfeeding management, when available.7,48
Step 3. Determine whether supplementation is required and supplement with care
1. The status of the infant requiring supplementation should be determined and any decisions made on a case-by-case basis (guidelines in Table 1).
2. Hospitals should strongly consider formulating and instituting policies to require a medical provider's order when supplements are medically indicated and informed consent of the mother when supplements are not medically indicated. It is the responsibility of the healthcare provider to fully inform parents of the benefits and risks of supplementation, document parental decisions, and support the parents after they have made a decision.50,51 (III)
3. All supplemental feedings should be documented, including the content, volume, method, and medical indication or reason.
4. When supplementary feeding is medically necessary, the primary goals are to feed the infant and to optimize the maternal milk supply while determining the cause of low milk supply, poor feeding, or inadequate milk transfer. Supplementation should be performed in ways that help preserve breastfeeding such as limiting the volume to what is necessary for the normal newborn physiology, avoiding teats/artificial nipples, 52 (I) stimulating the mother's breasts with hand expression or pumping, and for the infant to continue to practice at the breast.
5. Optimally, mothers need to express milk frequently, usually once for each time the infant receives a supplement, or at least 8 times in 24 hours if the infant is not feeding at the breast. Breasts should be fully drained each time. 53 (II-2) Maternal breast engorgement should be avoided as it will further compromise the milk supply and may lead to other complications. 54 (III)
6. Criteria for stopping supplementation should be considered from the time of the decision to supplement and should be discussed with the parents. Stopping supplementation can be a source of anxiety for parents and providers. Underlying factors should be addressed and mothers should be assisted with their milk supply, latch, and comfort with assessing the signs that their infant is adequately fed. It is important to closely follow up mother and infant.
7. When the decision to supplement is not medically indicated (Table 1), discussions with the mother should be documented by the nursing and/or medical staff followed by full support of her informed decision.
Choice of Supplement
1. Expressed breast milk from the infant's mother is the first choice for extra feeding for the breastfed infant.7,55 (III) Hand expression may elicit larger volumes than a breast pump in the first few days following birth and may increase overall milk supply. 56 Breast massage and/or compression along with expressing with a mechanical pump may also increase available milk. 57 (II-3)
2. If the volume of the mother's own colostrum/milk does not meet her infant's feeding requirements and supplementation is required, donor human milk is preferable to other supplements. 55
3. When donor human milk is not available or appropriate, protein hydrolysate formulas may be preferable to standard infant formula as they avoid exposure to intact cow's milk proteins and reduce bilirubin levels more rapidly, 58 (II-2) although recent data are less supportive of its role in preventing allergic disease. 59 (I) The use of this type of formula may also convey the psychological message that the supplement is a temporary therapy, not a permanent inclusion of artificial feedings.
4. Supplementation with glucose water is not appropriate because it does not provide sufficient nutrition, does not reduce serum bilirubin,60,61 and might cause hyponatremia.
5. The potential risks and benefits of other supplemental fluids, such as cow's milk formulas, soy formulas, or protein hydrolysate formulas, must be considered along with the available resources of the family, the infant's age, the amounts needed, and the potential impact on the establishment of breastfeeding.
Volume of Supplemental Feeding
1. Several studies give us an idea of intakes at the breast over time. In most studies, the range of intake is wide, while formula-fed infants usually take in larger volumes than breastfed infants.62–66 (II-3)
2. Infants fed infant formula ad libitum commonly have much higher intakes than breastfed infants.65,66 (II-3) Acknowledging that ad libitum breastfeeding emulates evolutionary feeding and considering recent data on obesity in formula-fed infants, it appears that formula-fed infants may be overfed.
3. As there is no definitive research available, the amount of supplement given should reflect the normal amounts of colostrum available, the size of the infant's stomach (which changes over time), and the age and size of the infant. Intake on day 2 postbirth is generally higher than day 1 in relation to infant's demand. 65
4. Based on the limited research available, suggested intakes for healthy, term infants are given in Table 2, although feedings should be based on infant cues.
Methods of Providing Supplementary Feedings
1. When supplementary feedings are needed, there are a number of delivery methods from which to choose: a supplemental nursing device at the breast, cup feeding, spoon or dropper feeding, finger-feeding, syringe feeding, or bottle feeding. 67 (III)
2. An optimal supplemental feeding device has not yet been identified, and may vary from one infant to another. No method is without potential risk or benefit. 68
3. When selecting an alternative feeding method, clinicians should consider several criteria:
a. cost and availability b. ease of use and cleaning c. stress to the infant d. whether adequate milk volume can be fed in 20–30 minutes e. whether anticipated use is short- or long-term f. maternal preference g. expertise of healthcare staff h. whether the method enhances development of breastfeeding skills.
4. There is no evidence that any of these methods are unsafe or that one is necessarily better than the other. There is some evidence that avoiding teats/artificial nipples for supplementation may help the infant return to exclusive breastfeeding20,52,69 (I); however, when hygiene is suboptimal, cup feeding is the recommended choice. 55 Cup feeding also allows infants to control feeding pace 68 (II-2). Cup feeding has been shown safe for both term and preterm infants and may help preserve breastfeeding duration among those who require multiple supplemental feedings.52,70–72 (II-2, I, I, I, II-2)
5. If bottles are being used, pacing the feed may be beneficial, especially for preterm infants. 73 (III)
6. Supplemental nursing systems have the advantages of supplying a supplement while simultaneously stimulating the breast to produce more milk, reinforcing the infant's feeding at the breast, enabling the mother to have a breastfeeding experience, and encouraging skin-to-skin. However, mothers may find the systems awkward to use, difficult to clean, relatively expensive, requiring moderately complex learning, and the infant must be able to latch effectively. 67 A simpler version, supplementing with a dropper, syringe, or feeding tube attached to the breast while the infant is feeding at breast, may be effective.
7. Bottle feeding is the most commonly used method of supplementation in more affluent regions of the world, but concerns have been raised because of distinct differences in tongue and jaw movements, and faster flow may result in higher (and unnecessary) volumes of feeds. 67 Some experts have recommended a teat/nipple with a wide base and slow flow to try to mimic breastfeeding and to avoid nipple confusion or preference,68,74 (II-2), but little research has been done evaluating outcomes with different teats/nipples.
Research Needs
Research is necessary to establish evidence-based guidelines on appropriate supplementation volumes for specific conditions and whether this varies for colostrum versus infant formula.
Specific questions include the following:
1. Should the volume be independent of infant weight or a per kilogram volume? Should supplementation make up for cumulative losses? 2. Should feeding intervals or quantities be different for different types of delivery of supplementation (e.g., bottles, cup feeding)? 3. Are some methods (type and delivery mechanism) best for infants with certain conditions, ages, and available resources? Which methods interfere least with establishing direct breastfeeding?
Notes
This protocol addresses the healthy, term newborn. For information regarding appropriate feeding and supplementation for the late preterm infant (35–37 weeks), see “ABM Protocol #10: Breastfeeding the Late Preterm Infant” 75 and “Care and Management of the Late Preterm Infant Toolkit.” 76 The World Health Organization broadened the annex of the “Global Criteria for the Baby Friendly Hospital Initiative: Acceptable Medical Reasons for Supplementation.” 77 to include acceptable reasons for use of breast milk substitutes in all infants.

|---|---|---|
| There is “no milk,” 5 belief that colostrum is insufficient until the milk “comes in” | Mother and family should be educated about the benefits of colostrum including dispelling myths about the yellow color. Small amounts of colostrum are normal, physiologic, and appropriate for the term, healthy newborn. | Can alter infant bowel flora and microbiome.86,87 |
| Potentially sensitizes the infant to foreign proteins.88,89 | ||
| Increases the risk of diarrhea and other infections, especially where hygiene is poor. 3 | ||
| Potentially disrupts the “supply-demand” cycle, leading to inadequate milk supply and long-term supplementation. | ||
| Supplementation is needed to prevent weight loss and dehydration in the postnatal period 5 | A certain amount of weight loss is normal in the first week of life and is due to diuresis of extracellular fluid and passage of meconium. | Supplementation in the first few days may interfere with the normal frequency of breastfeeding. |
| Supplementation with water or glucose water, increases the risk of jaundice, 90 excessive weight loss, 91 and longer hospital stays. 92 | ||
| Infant could become hypoglycemic | Healthy, full-term infants do not develop symptomatic hypoglycemia as a result of suboptimal breastfeeding. 15 | Same risks as for weight loss/dehydration. |
| Breastfeeding is related to jaundice in the postnatal period | The more frequent the breastfeeding, the lower the bilirubin level.93,94 | Same risks as for weight loss/dehydration. |
| Bilirubin is a potent antioxidant 95 and jaundice is normal in the newborn. | ||
| Colostrum acts as a natural laxative helping to eliminate meconium that contains bilirubin. 94 | ||
| Lack of time for counseling mother about exclusive breastfeeding when mothers request a supplement | Train all staff in how to assist mothers with breastfeeding. |
If the supplement is infant formula, which is slow to empty from the stomach
96
and often fed in larger amounts,
66
the infant will breastfeed less frequently. |
| Medications may be contraindicated with breastfeeding | Accurate references are available to providers (e.g., Medications and Mothers' Milk 2017, 99 LactMed on Toxnet website 15 ) | Risk of decreasing breastfeeding duration or exclusivity.9,10 |
| For most medical conditions, medication safe for breastfeeding mothers and babies is available | ||
| Mother is too malnourished or sick to breastfeed or eats an inappropriate diet. | Even malnourished mothers can breastfeed. Breast milk quality and quantity is only affected in extreme circumstances. Supplements are better given to the mother (with continued breastfeeding) than the infant. | Risk of decreasing breastfeeding duration or exclusivity. |
| Supplementation will quiet a fussy or unsettled infant 5 | Infants can be unsettled for many reasons. They may wish to cluster feed or simply need additional skin-to-skin time or holding.
67
|
Risk of decreasing breastfeeding duration or exclusivity. |
| Concern about the cause of frequent feeding and cluster feeding and other changes in infant behavior | Periods when infants demand to breastfeed more are sometimes interpreted by mothers as insufficient milk. This may happen in later weeks but also in the second or third night (48–72 hours) postbirth. |
Risk of decreasing breastfeeding duration or exclusivity. |
| Mothers need to rest or sleep | Postpartum mothers are restless when separated from their infants and actually get less rest. 29 | Risk of decreasing breastfeeding duration or exclusivity. |
| Mothers lose the opportunity to learn their infants' normal behavior and early feeding cues. 48 | ||
| Infants are at highest risk for receiving a supplement between 7 p.m. and 9 a.m. 102 | ||
| Sore nipples will improve if mother takes a break from breastfeeding 5 | Sore nipples are not a function of length of time breastfeeding. Position, latch, and sometimes individual anatomic variation (e.g., ankyloglossia) are more important.
