My 6 year old is experiencing very similar stomach ache issues. She is fine one minute and playing then starts complaining of a stomach ache. She is going to the bathroom constantly with small poops which have now turned into small diarrhea poops. Our doctor has been very passive with this issue and we are awaiting a stool sample results to rule out a parasite. Could it be constipation even though she is going to the bathroom so many times a day?
