My daughter is craving milk. she drinks it almost continuously. this is very unusual for her. she wakes up in the middle of the night to drink milk.

Can be a problem: Bovine milk is an easy source of calcium among other nutrients when used at any age over 1 yr. Unfortunately, some kids can overdue it to the point it becomes harmful."Milk cravers" can ingest it to the point they avoid other foods, but the excess can cause microscopic bleeding in the intestines and lead to severe anemia. You need to limit the kid to about 24 oz/day and go see her doc for testing.
