Our son, who will be 2 when we sail on the NCL Dawn is very close to being potty trained. If he doesn't have a diaper on he will run to the potty and go. He has never, ever, ever popped in a pool or a lake. He tells us when he has to go. So how will they know if he is or is not potty trained. Do they ask him, ask for a demonstration? If they are worrying about kids peeing in the pool, c'mon there are plenty of adults who do that!!! As far as pooping is concerned, not an issue. He will ask to get out and go. Is that considered potty trained?
