Our son, who is 10, has had issues with night time bed wetting. It has gotten better over the past few months. But for the longest time it was frustrating. We have him on Stratera, and that works wonders for bed wetting and AD/HD. Concerta does not work well for either. We have had him checked numerous times for bladder issues and he checks out fine.
We have also bought the bed wetting alarm from Amazon.com. The one that hooks into the underwear and the shirt and makes a buzzing noise and vibrates to wake the child as soon as he starts to wet himself. It helps train the brain to wake them up in the middle of the night to go to the bathroom.
Give him time. He just may need a little time to adjust to something, grow out of this, or have him checked out and make sure that he is healthy and that it is the right medication for him.
no,, it is common,, do not worry after some year he will not do this thing
