My 21 month old showed all the signs of being ready to potty train, and in particular was very good at sitting on the potty for 5-10 mins and even managed to do a couple of wees. So we started the next stage a couple of days ago and she managed a couple of wees on day 1 (and several accidents) and then five wees yesterday (plus a couple of accidents). We are using a star chart to reward her and she likes choosing the colour star for doing something in her potty. Today she has been happy to sit on her potty, but as soon as she starts to do a wee, begins to cry and stand up and move away even though she hasn't finished. She also is not showing any signs of saying when she wants to do a wee, but will sit when asked, and understands the words wee-wee, pooh and potty. Should I carry on as I am worried that the more she does in her potty the more distressed she is getting?
