Hi there!
We bought our daughter a potty seat when she was around your daughter's age. We didn't push the potty training though, we just thought it would be a good idea to have it in the bathroom so she could get used to the idea. I have not pushed her to it, usually she will come and sit on her potty if I am in the bathroom, and she does sometimes use it, although more often than not now she will want to use the big potty (I got her a seat that fits on it) rather than her chair.
