How do you handle children who don't know enough to tell you that they have to go pee, but continually pee on the furniture, carpet, etc. This little guy is almost 3 and he has peed here almost every day for the past few weeks....I have asked the mom that until he knows the concept of going to the washroom, that he be in a pull up and she brings him every day and does not tell me he's in underwear. All this peeing does a number on furniture....how would you handle this...would you leave him in underwear or make him wear a pull up until he knows what he is doing....frustrated part of toilet training.
