Quoting KiKi Dee:" My DD has been potty trained for a year now. However, every time she needs to go, she has the need to ... [snip!] ... she will potty on her self. Does anyone have any similar experience or advice on what I can do to show her she can just go?"
My twins are 4 1/2 and still announce they have to use the bathroom. It isn't as much asking for permission to go as it is habit. Since they were potty trained I always told them when they announced that they needed to go potty "Go ahead, you know where the bathroom is. Let me know if you need help".
