From what I've read and heard, potty training is so kid specific, you're bound to get a myriad of answers to your question. Here are some things that worked for us:
- Make a big deal out of it every time she does anything on the potty. I give stickers to my son, and "special" stickers when he poops (that's his hang up). The special stickers are of construction vehicles, which he adores.
- We also gave him a few day's notice that there would be no more diapers after the last box was empty. Then, we stuck to it and had him only wear underwear. He complained a little the first day, but has adjusted to the new normal.
- Does she watch you use the restroom? If it is something that mommy does, it may make her want to do it more.
- Have her wear some pretty underwear and comment on what a big girl she is now.
- If she asks for a diaper, take her right to the potty, even if she complains (but not if she throws a full out tantrum). My son used to complain sometimes when I brought him to the bathroom, but it was halfhearted and he would go in the toilet.
- Finally, if you think there may be something medical going on, make sure to talk to her pediatrician.
Good luck!
