From our boys being at a daycare for 7 years (well the oldest atleast)I have seen a LOT of kids that do not like to drink milk. Try adding strawberry syrup to it. That also depends on age. I started our 2 yr old on milk at 9 months, per the Dr, but we had no problem with it. Try adding syrup, that was the magic ingredient with the kids I have come across!

GOOD LUCK!
