My 3 1/2 year old BOY will not use the potty consistantly! If I ask him if he needs to go he says no then pees or poops in his pants. I have tried positive reinforcement, rewards, stickers, big boy undies. I am doing an average of 1 load a day of peed on and/or pooped on clothes. I have moved him back to pull ups and next back to diapers errrrrrrrrrrrr! Any suggestions would help!
