My 3 year old boy is being very stubborn with the whole potty training thing. He has gone in the toilet many times... but we can't seem to get the potty training finished. He will go days without an accident and then he will go a week with constant accidents. We are being really consistent with the schedule at daycare and at home. He will go on his own about 50 percent of time... the other times we have to remind him to go... and he does. We even have rewards set up for staying clean and dry... he gets to wear his "special" underware... and he really loves them. We have been potty training for about 6 months now. He has the muscle control to hold it and the cognition to know to go potty in the toilet... but he won't do it ALL the time. Any ideas?
