Hi L.,
Well I'm sure what really you should do but here is my advice.
I think you may want to just take a step back and see where she goes with it. Whatever you do "normally" like if she is in a pull up or whatever. I think I would just let her see it for herself, you know she can do it and she knows she can do it but she just needs to see it for herself.
So when you get her up in the morning either put panties on her or a pull up. Let it go from there.
Now this is one option.
Your other option, use up the pull ups and don't let her know you have anymore, only use them at night. So finish out this week and let her know that on Monday we no longer wear pull ups, we only wear panties and go from there.
When she does go give her praise and confidence, even call Daddy and let him know how much of a big girl she is. When she has an accident just say oh well better luck next time. And go on about your day.
You could also say throughout the day, Man I have to go pee, do you ?? And go together.
I don't know if any of this helps you, W.
