We thought it was because of milk products so we slowly (item by item-
milk, yogurt, cheese,etc.) stopped giving her anything with
milk in it. Then seven or eight weeks ago she started vomiting and never really stopped- she seems to cycle through one week of severe vomiting, 1 week of every other day vomiting and then one week of no vomit.. She throws up anywhere from 4 to 8 times a day and has been losing weight, she even wakes up in the middle of the night vomiting and dry heaving.
