|babies rarely need vitamin D supplements|
|The amount of vitamin D in human milk is small: 0.5-3.4 µg/liter (20-136 IU/liter) [Hamosh 1991, Good Mojab 2002] in mothers who are not vitamin D deficient. However, the vitamin D in human milk is in a form that is very easily used by the baby and therefore adequate for most infants, when combined with a small amount of sun exposure.|
|The best way to get vitamin D, the way that our bodies were designed to get the vast majority of our vitamin D, is from modest sun exposure. Going outside regularly is generally all that is required for you or your baby to generate adequate amounts of vitamin D.|
|World Health Organization information [Butte 2002, p. 27 ] states, "Two hours is the required minimum weekly amount of sunlight for infants if only the face is exposed, or 30 minutes if the upper and lower extremities are exposed." This guideline is from a study [Specker 1985] of exclusively breastfed Caucasian infants under six months old at latitude 39°N (Cincinnati, Ohio, USA). Darker skinned infants may require a longer time outside (three to six times the sunlight exposure) to generate the same amount of vitamin D [Good Mojab 2002].
It is not necessary to get sun exposure every single day, as the body stores vitamin D for future use. Per [Good Mojab 2003], "Studies have shown that children can store enough vitamin D to avoid deficiency for several months when they are exposed to only a few hours of summer sunlight."
