Thank you for your query.
Your child has constipation
Give him a laxative syrup for 14 days.Give plenty of fluids/fruits and fibre in the diet.
An enzyme preparation after food would be helpful.
Consult your doctor if the problem persists.
If you have any further queries you are free to consult me.
Hope this answers your query.
Wishing a speedy recovery.
Have a nice day.
