my 2 1/2 year old son drink some Chocolate milk Monday night with his supper and also had a glass yesterday morning.... at the sitters yesterday his nose started bleeding . could there be a connection here? It seems to only happen when he drinks milk especially chocolate milk. but eating chocolate candy bar doesn t have any effect on him. The weather has turned cool here and the sitter does have the heat on in her house. The nose bleeds dont happen every day but they do happen. The sitter told me yesterday the son was sitting on the couch ready a book and his nose started dripping blood , not a lot but enough that it had to be cleaned up with a tissue . The son s regular family doctor says its all due to the weather. A curious mom of a 2 year old, Jess Baker
