Hello my 4 year old daughterr was having stomach pains out of no where. She said she felt like she had to puke but couldn t. This went on for about 5 minutes. Then she layed on the floor and fell asleep. I got her to wake up and lay on me. She said her stomach doesn t hurt anymore but I m worried bnecause she didn t seem sleepy before hand and now she is really out. Do you know what this could be.
