A camper's soiled sleeping bag

On an overnight or at camp, if a young camper (7^th grade or younger) seems distressed in the morning and is either wadding clothes in their sleeping bag or wadding the sleeping bag (or their sleeping bag smells) they may have soiled their bed-clothes: enuresis, spotting or wet dream. You do not want to say anything direct, they are humiliated enough (even though no one else knows). But you can say in their hearing but no one else's, “I think I'll get my sleeping bag washed today, want me to throw yours in too to make it a load.”
