Quoting ThatsAlotaNuts:" He is only 2 next month, i dont think he is ready for potty training, we did try but he was just climbing on the toilet for no reason never when he needed to go."
Have you tried turning it into a game? Thats what we did with DS when he went through that phase. Also we make sure he has something he can play with that will distract him while we actually changed him. Give him lots of reassurance, and praise. If you get frusterated do your best to hide it from him, because that could be upsetting him too.
