At DD's 1 year the doctor said to keep her around 20 oz of milk and to transition her to milk at meals from a sippy. That means around 6oz per meal to only be at 18. I cannot see her drinking 6 oz like that, even though I guess she does do it from a bottle. Right now she will drink 2-3 from her sippy and then gets the rest in a bottle to finish. What are your little ones doing?
