S.M.
i was told by my pediatrician to start vit d milk at one and to do both sippie cup and bottle at 6 mos so that at one yr they are able to do just a sippie cup. and at one then again i am on wic so they told me at one stop formula and do reg milk. and i get the 7 and 10oz sippies and he gets pleanty of milk an juice. i usually do juice throughout the day and milk at night. but once he falls asleep put water in the cup so if he gets thirsty at nite he can drink water cuz they shouldnt go to bed with a milk bottle cuz it will ruin their teeth...hope this helps
