Hi S.,
I have a son who is also 2 1/2 and potty trained himself. So wonderful that was. Going #2 was not a big issue for us after the first few times. I do recall then and even still, when he hasn't gone in a 24 hour time frame, his poop is hard and it does hurt him to be released. I try to make sure his eats and drinks things that help keep his stool soft. ie. raisins, raisin bran, granola bars, mini wheats, juice, watermelon, etc. Reading books or rubbing his back or singing songs has helped to get his mind off of pooping. His body then relaxes and it becomes easier for him to go. I'm sorry if this is to graphic, but, i went #2 once or twice and showed him, then we would flushed and say " bye bye poopie" (which we still do). Alot of the time its been very helpful to my son just to sit on the "big" toliet while he was on the potty chair trying to go. He does need to get over the fear of it. He fear could possibly be thinking "something is coming out my body and then we are just going to flush it away". After a few times of this he caught on right away. We havent had any accidents- #1 or 2 in about 2 months now. He does still sleep in diapers at night however. That will be our next battle, soon enough.
Good Luck
