This is particularly a problem for darker skinned infants, and those living in more northern locations with limited sunlight exposure during winter months.
Vitamin D serves as an essential nutrient for bone health by promoting calcium and phosphorus absorption from foods. It has also been shown to bolster immunity and decrease the risk for certain chronic diseases such as diabetes and some cancers.
Unfortunately, many mothers who are breastfeeding their infants neither supplement themselves nor their babies.
To combat this potential for vitamin D deficiency, the American Academy of Pediatrics recommends that breast-fed infants begin vitamin D supplementation starting within the first few days of life, at a dose of 400 I.U. per day. Babies fed adequate amounts of standard infant formula receive enough vitamin D and do not need an additional source.
Unfortunately, many mothers who are breastfeeding their infants do not follow this recommendation — they neither supplement themselves nor their babies. A recent study explored why so many mothers are failing to supplement their infants and the methods of supplementation they preferred.
The researchers surveyed 236 mothers of infants at either their 2-month or 4-month well child check and reported results for 140 exclusively breast-fed and 44 breast- and formula-fed infants. Slightly over half of the infants had received vitamin D supplementation, but less than half were receiving the recommended dose of 400 I.U.
Mothers were more likely to supplement the babies if their health care provider had recommended it. Women of color were also more likely to supplement their babies.
The reasons women gave for failure to supplement included being unaware of the guidelines and/or risks of vitamin D deficiency; believing that breastmilk is nutritionally adequate; and feeling that their babies did not like the taste of the vitamin supplement.
Parents of newborns who choose to breastfeed need to make sure they are giving enough vitamin D to their infants to ensure optimal bone health — either by giving their babies vitamin D drops directly or supplementing themselves adequately. Don't hesitate to discuss any concerns you may have or the proper dosages with your child's doctor.
