Should my formula fed baby take poly-vi-sol or wait until he is on solid food only?

Baby vitamins. Babies get their vitamins from formula except the breast fed babies need vit d supplements.I recommend my babies to start polyvisol IG they live in an area whare thereis flouride in the tap water at age of 4 months.If they need suplements of flouride i will give them polyflor vitamins i agree with most who are opposed to supplemnting vitamins, but as long as you dont use mega doses, no harm will com.
