I found that training pants just didnt work here.
It was nudie or nappy. If she was wearing her training pants (the best and less ones) she just weed in it. Even if I explained to her it wasnt a nappy. I guess it was the feeling of something there that gave her the confidence to wee in it.
So we did the nudie thing for a while and now she is nappy free at home. She wears undies sometimes but its easier at home to just have trackies so she can get it off quickly.
She still goes to childcare with nappies but we are going to try undies soon.
I would wait with the childcare until Becky is going confidently at home
