Thanks for the tips everyone! We have gone straight to 'big girl knickers'. I brought about 20 pairs from Kmart (in packs of 7 for only a few $$ each), expecting to go through the majority in one day. I'm not expecting tomorrow to be as successful as it won't be such a novelty, but we will see.

I put a nappy on her for her day sleep today and one for night time. Before her day sleep she'd just done her first wee and as soon as she woke up she said 'potty' so we rushed there, took off her nappy and straight away she weed. It'll be interesting to see what she does in the morning.

I will see how she goes tomorrow and might get a few of the pull ups for going out - I don't want her to go backwards though (if she wants to continue that is).
