my boy is 7 year old. he has problem of bed wetting every day please suggest me what to do

A. Hello good evening !! Make kid pee before bed time and in the middle of the night ,continue this for 1-2 weeks ,then he gets habitat to this routine. As it is winter and due to intake of water,fluids might cause this. If you observe daily and no change even after this then he might be due to health condition check with the Doctor.
