Vitamin D Supplement For Baby Articles & Resources

Vitamin D-deficiency rickets is a public health issue that warrants attention, but not at the expense of breastfeeding. Media attention has mainly focused on exclusive breastfeeding as a cause of rickets; however, an increase in rickets cases may result from the reduced amount of time that people spend in the sun and from women who do not have adequate stores of vitamin D during pregnancy.

It is true that breastmilk has low amounts of vitamin D, but those low amounts are just what breastfed babies need. In rare cases, vitamin D supplements may be appropriate for some breastfed babies, such as those not exposed to the sun because of their parents' religious beliefs and those who live in regions that do not receive plentiful sunshine.

Experts say that darker skin makes children more susceptible to rickets. This is because darker tones tend to protect the skin from a certain amount of ultraviolet rays, causing an almost natural deficiency in vitamin D. Michal Young, MD, a noted neonatologist and prominent advocate of breastfeeding in Washington, DC, explained, "`Dark-skinned' is a relative term and given to far too many variations. Also, climate conditions, such as cities with a lot of air pollution, can make sunlight a challenge for persons who are not as deeply pigmented."

Are African American or darker-skinned babies as susceptible to rickets as those who live in areas where sunlight is diminished? "Most babies with light-medium skin tones need only a little outdoor time, while darker-skinned babies need more outdoor time. Let's get the kids outside more, instead of giving them vitamin D," says Katherine Dettwyler, PhD, adjunct professor of anthropology and nutrition at Texas A&M University.

A natural alternative to vitamin D supplementation is exposure to sunlight, but how much sunlight? To make enough vitamin D, a baby in only a diaper needs a total of only 30 minutes of sunlight a week--less than five minutes a day. Fully clothed and without a hat, a baby would need two hours of sunlight a week, or about 20 minutes a day. Medium to darker skin tones need a little more time in the sun.

Becky Saenz, MD, IBCLC, associate professor of family medicine at the University of Mississippi Medical Center, believes the AAP may have concerns about recommending sunlight exposure because of the danger of skin cancer. She points out, "There is a vast difference between recommending that it's okay for baby to sit in the grocery buggy while mom puts the groceries into the car in the early morning or late afternoon, and recommending nude sunbathing at noon."

Maternal Diet: Another Possible Alternative?

Maternal vitamin D status is crucial to the vitamin D status of the breastfed infant. The amount of vitamin D stores a newborn baby has is directly related to its mother's vitamin D stores. Several studies have documented that the vitamin D status of the mother can be raised by increased exposure to UVB rays, supplements, and increased consumption of foods with vitamin D. For instance, healthy individuals who eat two to three servings of salmon per week have met all their vitamin D needs. Salmon is also an excellent source of docosahexaenoic acid (DHA), the long-chain polyunsaturated fatty acid essential to visual and brain development. DHA is found in human milk but is absent from most infant formula. The amount of DHA in breastmilk also varies with the maternal diet. And just as with vitamin D supplementation, some people are looking to cash in by adding DHA to infant formula. Fortification of infant formula with DHA has a potential value of $300 to $400 million for the science and technology industry. (1) Just as the March of Dimes promotes the pre-conception use of folic acid as a way to reduce the risk of birth defects, public-awareness campaigns could promote the importance of women's vitamin D status in their child-bearing years.

What's a Mother to Do?

Among experts in the pediatric and breastfeeding fields, there is a lack of consensus about the issue of vitamin D-deficiency rickets. Many breastfeeding advocates have a problem with a "one size fits all" approach to vitamin D supplementation. Some headlines have claimed that, with a growing number of African American women choosing to breastfeed, there has been an increase in the number of reported cases of vitamin D-deficiency rickets. This misleading statement in effect questions the ability of African American women to provide quality nutrition for their infants. It also perpetuates the myth that technology and science are needed to complement and improve breastmilk.

Another potential result of this type of recommendation is that women may choose not to initiate breastfeeding at all. Among African American women, breastfeeding rates are often 20 percent or more lower than those of whites and Hispanics. Breastfeeding promotion in the African American community has long been a challenge, and this recommendation may actually deter African American women from breastfeeding. Consequently, both mother and infant would miss all the benefits associated with the breastfeeding experience. Katherine Dettwyler says, "It makes it more of a hassle to breastfeed, and it makes it sound as though breastmilk is lacking while formula is perfect. Already, too many people think formula is a risk-free option to breastfeeding, when it clearly isn't. I'd like to see some side-by-side comparison of the risks of rickets from lack of vitamin D in breastmilk to the risks of everything else from [the] lack of pretty much everything in formula."

Breastmilk is the only form of nutrition designed to meet a baby's specific needs. Some babies have circumstances that warrant medications and/or supplements; but these should be given on a case-by-case basis. If experts begin to say that breastmilk is best but that all breastfed babies need a supplement, of any sort, a Pandora's box is opened. Formula companies will heartily feast on this information. Their marketing may include tag lines such as, "Formula X has everything your baby requires, so there's no need to worry about rickets." In fact, formula manufacturer Mead Johnson has already capitalized on the belief that breastmilk is not quite enough. Advertising for its product D-Vi-Sol (vitamin D drops) says, "With Breast-feeding and D-Vi-Sol Baby's Nutrition is Complete. D-Vi-Sol--A daily dose of peace of mind. You know that breast-feeding is the best form of feeding you can give your baby. However, even the superbly balanced nutrition of breast milk contains only about 10% of the recommended daily intake of Vitamin D for infants."

This ad tells the consumer and the general public that breastmilk alone is not good enough for babies. Formula manufacturers will gain in a number of ways from this kind of recommendation, and their marketing will begin to send subtle messages that their products are more complete than breastmilk. Sales resulting from a universal recommendation of vitamin D would also provide more residual income for the formula companies at the expense of exclusive breastfeeding.

We need to be very cautious when professional organizations make broad policy statements that have huge health implications. Not all babies are at risk of developing rickets; too much vitamin D, in fact, can cause an excess amount of calcium in a baby's system, potentially leading to kidney or brain damage, lethargy, seizures, comas, pancreatitis, or cardiac arrhythmias. What happens if a baby is given an overdose of vitamin D drops? What if a mother chooses not to give the drops? Who will pay for the drops? What if a mother can't afford to buy them?

Medical doctors will also be affected by this recommendation. Some will prescribe the drops across the board rather than on an individual basis. For those doctors who don't promote breastfeeding to their patients, this recommendation may reinforce the doctors' lack of confidence in breastfeeding as the most viable option.

Many unanswered questions regarding the supplementation issue remain. What are the short- and long-term health consequences of providing vitamin D to infants who are not vitamin D deficient? What are the psychological and physiological impacts on breastfeeding? Have the risks been weighed against the benefits? Clearly, there is a need for additional research on breastmilk, vitamin D, rickets, and the disease's causes and means of prevention.

A Brief History of Rickets

Before African Americans moved in large numbers to northern cities after World War II, their babies received vitamin D almost entirely from breastmilk0 the primary nutrition for most infants during that time, and from UVB rays. Many African Americans worked as sharecroppers and spent well above the current recommended amounts of time in the sun. Although cow's milk was fortified with vitamin D in the 1930s, most African Americans did not buy or consume commercial milk but instead relied on the milk produced by their own cows, which was not fortified.

In the 18th and 19th centuries, the prevalence of rickets was as high as 40 to 60 percent among children in inner-city neighborhoods in England, Germany, Poland, Scandinavia, Canada, and the US: The 1960s, 1970s, and 1980s saw a further emergence of rickets among exclusively breastfed infants of some Asian and Muslim women in northeastern US cities. The common factor among these groups was that the women were heavily robed; only their hands and faces were exposed. In the 1990s, there were additional rickets cases in exclusively breastfed African American infants?

Informed Consent

If your healthcare provider suggests vitamin D drops for your baby, you may be confused. You've read the literature and know that breastmilk is the best form of nutrition for babies. You've never come across any information on vitamin D deficiency. What are you going to do? How can you decide?

It may help to have the following questions at hand to ask your healthcare provider:

* What is rickets?

* Is my baby at risk of developing rickets?

* What are my options?

* Will it help if I increase vitamin D in my diet, through foods and/or supplements?

* How much do the vitamin D drops cost?

* Will my insurance company cover the cost?

* What if I choose not to give my baby the supplement?

Above all, know that you have the right to make the final decision--and the right to trust your own intuition about what is best for your baby.
