Maybe ya'll can confirm/deny my suspicions...
DS2 is 9 months old. At his well-check, his (very pro breastfeeding) pediatrician recommended vitamin D supplement because "breastmilk is low on vitamin D". I mentioned that take a vitamin D supplement, and the pediatrician said that didn't matter; that vitamin D is not soluble and doesn't transfer well to breastmilk. I knew that was the case with iron, but I'm pretty sure that's not what I'd read about vitamin D.
So... is vitamin D soluble or not? I do know that the amount in breastmilk has much greater bio-availability than supplements. We also live in central TX, and take walks outdoors every day, so I'm not entirely sold on the need to supplement in any case.
What do you ladies think? (Yes, I realize this ya'll cannot offer a medical opinion, I'm just curious what ya'll think.)
