M.D.
I have an almost 3 year old girl (so I don't know how different that is) who is still not potty trained. I tried off & on when she seemed interested but the interest would pass and then she would get upset at my attempts to get her to sit on the potty.
I finally just decided that she will let me know when she's ready. I had a baby 5 months ago and I knew it was NOT the time to try. But then suddenly two days ago she has started asking to go potty....AND she has pooped on the potty the last 2 nights before bed! It was completely HER idea and I think that is what is working.
Some kids get it earlier than others, but the key is to not push or get frustrated. (easier said than done I know) :)
Good luck!
