Fantastic! I'm not even sure you will need a reward chart .

One thing though - after reading an article about wees etc (sorry, I can't remember the words my brain has melted), it might be ok NOT to remind her to go. Best that she feels it herself and responds herself when her bladder is full, because that is the right time to go.

It might be time for a trip to the shop to buy some undies for your big girl. I love teeny undies, they are so cute!
