My 9 year old sister has morning sickness and she has been having them for over a month. She usually has it just after waking up before going to school. Sometimes she vomits and sometimes she doesn’t. When she does vomit it is just spit and fluids. When going to the toilet everything is fine (in terms of peeing and pooping). First we thought it was because she didn’t want to go to school. When we tell her to stay she doesn’t want to. We thought it was the heat but we have airconditioning.
