Tting

Dd is doing well with Tt, she's only in nappies for her day sleep and overnight and when we are out, otherwise always in her big girl undies. The problem is that she seems to have control over stopping her wees but not starting them. If she starts to go she can stop after the tiniest trickle but then we are in the potty reading books and singing songs for up to half an hour. I've tried not entertaining her but then she won't sit there and we get an accident. Any ideas or is this just part of the process?

She woke up tonight and called out to me and told me she had a poo and asked for her nappy to be changed. I did it and she went straight back to sleep. She's very aware of poos?
