Hi my 2 1/2 year old has decided she doesn't want to wear nappies anymore and asked to start using big girl pants like the other children at nursery. It's been a week and she still hasn't actually started using the potty and just wets herself. She sits on the potty for a while then says "not coming mommy" and gets up. Should I give up and discourage her from potty training or should I Alfie it another week? Please help! X
