S.M.
I agree with mum4ever. Put him in the overnights for older kids under his PJ's. Send him with bags to put them in when changing in the morning. My DD who is 13 now, wet the bed till she was almost 13. She still has the occasional accident, but they are very rare now. She wore the overnights all the time. If she was going to stay with a friend that didn't know her "secret", she could easily hide it. We tried the meds but the didn't work for her. I have friends who used the meds and they worked great with no side effects. If you are going to try the meds, start them now to see if they will work. If they don't, send him with the overnights. Best thing ever, especially for the older kids.
