Dear Mom,
Your daughter is well within normal limits for not being potty trained yet.
I encourage you to make sure that you have a child’s potty seat in the bathroom or a small seat that you put on your toilet. Have some books beside it and periodically have her sit on the seat and just read books.
Once you see that she is showing signs of interest take her to the store and have her pick out her own “big girl” underwear and tell her that as soon as she starts using the potty instead of her diapers, then she gets to wear them.
Hang in there, she’ll get there. I’ve never had a child go to kindergarten with diapers.
