Vomiting in middle of the night
My daughter, who'll be 4 in July, has begun vomiting in the middle of the night. I'm sure if she wakes up when she does. But it seems to be one violent act and then it's over. This began a while back and doctors in our town (and we've seen over half of them) are clueless and continue to throw random drugs at her. It when on for about 2 weeks then stopped and now it's back. She seems to be fine during the day (never vomiting or complaining about stomach pains) it's just these occurrences which happen between 2 and 3 in the morning. We've removed all the toys from her room, bought her a new mattress. We're just at a loss of what could be causing it.
Any help on where to go next would be greatly appreciated.
