Welcome to Ask The Doctor. Thank you for your query.
It is not normal for any child above the age of 5 to wet his/her pants. Some kids develop bladder control at late ages but almost none will not develop it by their teens.
There can be a neurological cause or a Development issue which has led to this. The best way to combat this would be to consult a Urologist who will first try to find the cause.
The treatment can be behavior therapy and water restriction in some cases and if needed, surgery can be undertaken.
