my daughter is wakingup at night and throwing up

[mlarned]

the last two nights my daughter has woken up at 4am and thrown up. she is eating normally, and going to the bathroom fine. She does not have a cold, and is her normal active self. After she throws up she goes right back to sleep and wakes up fine in the morning. Should I be concerned about this?

not if its just a couple of nights but if it goes beyond that then yes a check up would be a good thing, does she eat late at night before bed ? How old is she ?
