Hi welcome to Healthcare magic forum.
Thanks for asking a question to H.C.M.Forum.
Your 7 year old daughter is suffering with epigastric pain
of abdomen, more in the morning and night before bed.
It appears to be due to indigestion
due to new foods, gastric irritation due to more spicy foods, worms in the intestines, or urinary tract infection
, rarely may be due to lactose intolarance. etc.
I advise you to consult a pediatric specialist for diagnosis and treatment, you may need to get the stools examination for reducing substances, or cysts and ova.
Wishing for a quick and complete recovery.
