At least for the time being, wear Depends when you go to bed.
yes im a heavy sleeper n lately since i took sum time off from skool ive been sleepin alot durin the day so at night i stay up late but i wud get up early mainly wen i figure out ive wet the bed
Two questions. Do you get enough sleep? Are you a heavy sleeper? I can see where if you are exhausted you might fall into a very heavy sleep and wet the bed.
You should be checked out by a urologist. This happens usually in younger kids and by the time they hit puberty, the brain and bladder are communicating and no more wetting the bed. For my son it was like a light bulb went on and it stopped. He was about 11/12 or so.
Since this is not normal you really need to make an appointment with the urologist. In the mean time maybe try to use some Depends so that at least the urine is contained when it does happen.
