Geneva is 6 and occasionally wets the bed at night if she has something to drink after 7 pm. She goes to bed at 8:30 and pees before bed. Sometimes she balks at my request to go to the BR, but I just ask her if she likes peeing in her bed and she says no and goes to the bathroom. I keep a special pad on her bed in case she does wet the bed, so it wont make her matress reek (I can't stand the smell of urine). Also, if she does make a mess, she has to be the one to clean it up, wash the sheets, and help make her bed. I don't know if this helps you, but there's my advice (also, if they aren't your children, maybe the one in charge of them should care for them)
