Potty training my 3 year old.


So for you other moms out there. This is my second and I'm still working on potty training my daughter but she has regressed and I can't figure out why. I spend lots of time with her when I'm not at work. Every time I ask if she needs to go potty in the last two to three months she will tell me no. There are some times where she will go by herself. I just don't know what to do and really don't want to be having to buy diapers and pullups. Any tips or advice?
