my little boy has been potty trained since before he started nursery last September. We started late since i didn't he was ready but he got using the potty and toilet pretty much right away with the peeing. But he has never gotten the pooping. He isn't scared, i think he is just lazy but i don't know what to do. He is almost 4 now! there are days he'll go 5-6 times. I've tried rewards, punishment, yelling, saying nothing and even having him clean up himself so that he sees how much work goes into it. he doesn't care! Please, can someone help me? Anyone?!
