Just got back from our 6 month dr appointment and the dr gave LO a prescription for multivitamin - (polyviflor or something like that?) I feel like I haven't heard many bees give their babies vitamins (other than vit D maybe) and was wondering whether it is unusual to need a multivitamin so young? He is breastfed and supplemented with formula. Anyone else give their LO a multivitamin? which one?
