My son just turned 3 and for the last year we have had a potty and we put him on it before/after naps and morning/night. This week I dedicated myself to fully potty training. I even made a reward chart. He is fine if I just put him on the potty every so often but day 3 and he will still pee himself and just not care! He wont tell me he has to pee and wont even tell me if he has already peed. He fights putting on underwear. I'm being very positive and encouraging and always reminding him to tell me when he has to go but nothing is working. Is he just not ready?? Or should I keep at it?
