Hello.

My 7 year old daughter has had trouble sleeping the past 3 nights. She has been sitting up and gagging. We have gotten her to the bathroom before she actually got sick the past 2 nights. She sucks her thumb, so I don't know if that has anything to do with the problem or not. She also complained of bad dreams the first two nights. She does not exhibit any symptoms during the day. Her appetite is normal. We have also been active during these past three days. Two of the days we were outdoors for several hours. She may have had more "junk food" than normal, but nothing excessive.

I'm beginning to worry since this has happened 3 nights in a row.

Not sure your area there is a virus or illness going around locally here that includes this

Does she have reflux problems?

Hmm... that's quite strange
