Many children don't 'get' the concept of pull ups, to them, it's just a diaper. Do you want me to pee in my pants or not? In my opinion giving the pull ups, sort of gives them permission, but I also know children who adjusted very well with them, so it really depends on the child. I'm going to give you some suggestions, but it really boils down to the fact that when she is ready, she will go. You've done everything you are supposed to do on your end, but she's the one not quite ready to give in. Some children has a real issue with seeing the bm go down the toilet, it feels like they are letting go of a part of themselves, which is scary.
I welcome your thoughts, let me know if you want to talk more.
Another expert made a point that I forgot to mention. You may want to invest in plastic sheets and forgo the diapers at night period. No liquids for two hrs before going to bed or nap.
Do you have any other questions?
