Thanks for the query to H.C.M. Forum.
In my opinion your child may have hyper acidity and gastritis
Cause of hyperacidity
may be overeating , fried food , junk food, spiced food.
Nausea develops due to hyper acidity and this is a common feature among children of this age group .
In my opinion blend diet will help the little one .
Control of diet is one of the best treatment.
Still feel nausea antacid
tablets for few days will help. ( PANTOZOLE +DOMPERIDONE
