I'm a FTM and EBF and at our 3 week checkup my pediatrician said to start giving our son D-Vi-Sol, a vitamin D supplement made by Enfamil. He told me vitamin D doesn't transfer well through breastmilk and most children who EBF have deficiencies. Anyone else giving this to your little one? So far my son takes it down like a champ and it doesn't seem to bother him at all!
