Multivitamin for 11 month old

Hi mommas,

Needing some advice...my babe just started drinking homogenized milk. Doctor said to start introducing it. Well, now he flat out refuses a bottle (formula)and only likes his sippy with cold milk. Only time I can get him to drink a bottle (formula) is first thing in the morning.

Im worried about him getting enough vitamins as the formula has so much of them in it. Should I get my babe on some sort of multivitamin? I'm thinking he is done with his bottle and formula. He wants to be a big boy Haha.
