I recently took my 16 month old to a WIC appointment. The nurse commended me for continuing to breastfeed, but told me that breast milk is nutritionally deficient past 12 months, and that my DS needs to drink Vitamin D milk in order to get the proper amount of fat, protein, Vitamin D and calcium needed for brain development and healthy growth..She said that past the first year, breastfeeding fails to provide any of those. I told the nurse that my DS still nurses 3-4 times a day in addition to drinking almond milk twice a day (he can't tolerate soy or dairy) and eats a varied diet (LO is in the 85th percentile for both height and weight so he's not starving). She said there's no way to know if breast milk is still meeting LO's needs because we can't measure how much he's drinking. I'm convinced that DS is getting the proper amount of calories, fat, etc but she kept pressuring me to reintroduce cow's milk.
So, my question is, is breast milk only "what's best" for the first year of life, but somehow cow's milk magically becomes "best" once a child turns one? Will my child still be healthy if he depends on breastmilk or non-dairy milk for his calcium, and Vitamin D as well as healthy foods for fat or protein?
Really, I guess I'm looking for validation about my decision to continue to nurse my toddler lol.
