I have started potty training my 2 1/2 year old girl as she asked for pants. However, I am having no successes on the potty or toilet, but find that she wees within 2 or 3 minutes of me taking her off, every time, which is getting frustrating. I have tried leaving her on for longer, and taking her off then putting her back on a few minutes later, but she seems to manage to hold it until her pants are back on! Any suggestions appreciated.
