DD being sick in her sleep - any ideas?

[toomanyeasterbunnies]

My DD is 6 and last weekend she was sick in her sleep. I don't think she woke up when she was sick as I didn't hear any crying or any other noise to suggest she wasn't feeling well. I assumed she was sick from too much excitement as we had just been to Alton Towers that day. I kept her off school for a day and she was absolutely fine.

Last night she has been done it again. Her bed is covered, its up the walls and yet she still slept through it!! I am a bit worried that there is something going on as she is fine in every other way and has never really been a sickly child (IYSWIM). Any ideas as to what might be causing this?

wat had she eaten last night?

Ds1 was randomly sick after having pepsi max for the first time (he had never had cola before)

It gave him an awful headache too.

Could it be something she ate or drank?
