Dd has just turned 2 was hoping to do potty training when it was a little bit warmer. But she keeps asking for her nappy off. I take it off if she has recently pooed, which is usually not long before bedtime. She has only actually weed once without the nappy and wasn't really aware I don't think until she was wet. I didn't see her face so can't say for sure. How do you know when they are ready?
