Hi K., First of all, there is probably nothing wrong with your son at all. Night wetting is not an unusual problem for older children. It is just not something most of us talk about. I have a 13 yr. old who still has issues with bedwetting. (he'd just die if he knew I told). We first asked our Prediatrician, they told us the exact same thing they told you! Then as my son started puberty we decided to persue the issue with a urologist. We wanted to just make sure there really wasn't something wrong. My son had an ultrasound and and x-ray, not to mention a visual exam of his parts. One thing that the x-ray showed was that his colon was very full (of poop)and enlarged. They said his wetting may be caused by the colon pushing on the bladder at night. They gave him a bunch of laxatives so he'd have loose bowels for a week or so to shrink the colon back down. We sort of did it half-heartedly. I thought that was just plain stupid as my son is also a seriously heavy sleeper. We started making sure he was pooping every day, which he was, and didn't take that any further. Then I asked a bunch of other people about the subject and here is what we have found helps... no caffine after lunch, limit sugar and drinks after dinner, and making sure he is sleeping as long as he needs. If waking him up in the morning is difficult, then he probably isn't getting enough sleep. Kids this age sometimes need 12 hours. We tried getting him up at night to go, and that sometimes helped, but usually not. He'd get up at about 1 am, use the bathroom, go back to bed, and be wet by 3 am. I have no idea if any of this info will be helpful, I feel like I am rattling on and on. Good Luck, you are not alone!
