Hello, thanks for query.
I would like to say that there are two possible reasons of pain abdomen in your's daughter case.
( Competition of & in study).
Hyper acidity i.e. gastritis
3rd possible reason may be over feeding by herself and by parents due to affection to their child.
In my opinion pl take it very easy and be relax
. Let the child live normal life.
Good luck for child. Dr. HET.
