DD is 2.3, I've been asking her if she'd like to use the potty before her bath since Xmas (she gets read an extra story while she sits on it) and in the last couple of weeks she has asked to sit on it & done a few wees & one poo 
I'm wondering what to do next... I've started asking her if she wants the potty at other times, but she's not shown any interest yet. Should I be letting her be nappy-free more often? Putting her in pull-up nappies? Or just carry on asking her until she shows more interest?
As an added complication #2 is due in April, but for a variety of reasons could turn up any day now, and I'm not sure that I really want to be chasing DD around the house with a potty while trying to feed a newborn!
Any thoughts?
