My pediatrician told me my 14 month old needs about 24oz of milk, BUT that INCLUDEs yogurt,cheese, and milk products. So you can deduct and judge with that.
If you are worried that your child isnt getting enough milk, there is a supplement called poly-vi sol (i think thats the name). its a supplement for when a child doesnt get or wont take enough milk.
in the end, i would call your pediatrician though.
