My son is just over 3 1/2 and should be starting junior kindergarten in September. I started potty training him a little over a year ago and we have made no progress since the beginning. I will sit him on the toilet and if he needs to go pee he will, that is pretty much the extent of it. For months now he has been going commando at home because if he wears a pull up or underwear or pants he will just pee in them. I was hoping that with nothing on he might tell me when he needs to go but he doesn't he just holds it until I get him on the toilet or until he can't anymore and pees on the floor. He also will not poop on the toilet he will just hide somewhere and go right on the floor. He doesn't seem to be bothered by the mess. It seems to me like he is perfectly happy to just go wherever he's standing and has no motivation or interest in being potty trained not even when I bribe him or try to make a fun game of it. I'm told he can't go to kindergarten unless he is fully potty trained. I feel like I have tried everything I or anyone else can think of and I am at a loss. Is there anyone else who has experienced something similar? What did you find helped?
