I am on the verge of mental break down. I have been potty training my son for 3 months now and he still has constant accidents and he could care less. I started training my son at 18-months-old and had success early on. He still averaged about one accident a day and some days would have none. However, the last few weeks he only has success when we are home and he is naked. Anytime he is wearing (thin) underpants he pees and poos in them. He also pees and poops in his high chair and he bathtub while naked. He does not care. I cannot keep cleaning up these messing. I am losing my mind. Please, please help!!!
