Hi, My 9 year old daughter wakes about 1 to 2 times a month and comes to our room upset...we ask her if she going to throw up and she says yes. Usually she is better in a few minutes...does not throw up and goes back to bed. On the ocassions she did throw up it would be one time and she would feel better and go back to bed. Last night it was the worst I have ever seen. After talking with her I discovered she is having a reoccuring nightmare....she threw up last night and was better almost immediately and we acutally had a snack together and lauged about some things. Should we be alarmed and is there anything we can do?
