My son is almost 11 years and still wets the bed, about 2x/week. He is going on a school trip and will be sleeping away for 3 nights. I am worried about his potential embarrassment, either with sending a disposable pad that friends could see, or of course if he wets. I understand there is a pill he can take for those nights to help with this, but I have not researched it. Alternatively, I can coach him to have no liquids after a certain time...suggestions?
