I'm not sure what to make of my son's potty situation. He turned two at the beginning of April, which I know is young but he seemed ready and interested in training so we tried and right from the start he has indicated when he has to pee and consistently goes on the potty. We never make him sit on the potty, except before bed to try. He'll even hold it for awhile if we can't get to a toilet quickly, He tells us when he has to poop to, and will sit on the potty for long periods of time, of his own accord, but when he feels the 'urge' he freaks out and won't go. He will spend all evening running back and forth to the potty, or just sitting on it for a long time, and maybe get a teeny little poop out. We've started offering him a diaper to poop in but he does the same thing and asks us to take off the diaper so he can sit on the potty. At this point I just want him to poop already, no matter where it is. I'd love some advice or suggestions on what to try, I'm not sure what he is afraid of, other than the sensation maybe. He loves to flush his pee and he isn't pooping on the big toilet yet. Help!
