Just some advice on how to move forwards - if anyone can help that would be great.
I have boy/girl twins. DS has taken to potty training like a dream. After day 2 we haven't had any accidents and he's able to say when he needs to go (or not go). Now 10 days later and everything's still rosie. Brilliant!
His sister - what a contrast!
Determined and intelligent young lady who has decided she doesn't want to get rid of her nappy. I know she knows what it's all about, she says 'Look mummy, Isaac's done a wee wee in the potty, good boy Isaac. Let's get him a chocalate button'. (Ashamed to say we've resorted to chocolate as a potty reward - but then I'm raising/training twins - I've decided I deserve a medal). 
We bought a potty months ago, decorated it with PPig stickers, played with it etc and when wearing her nappy during the day, she'll often do a wee wee on the potty - BUT SHE WANTS HER NAPPY PUT STRAIGHT BACK ON! We've bought pretty knickers, tried a sticker chart, bought Polly's Potty Book etc but she's still not having any of it.
I wonder if she's sees it as a comforter. She is still reluctant to give me her dummy every morning but we insist and she does. But with the potty we just can't force her. Nursery did a cold turkey approach last week with both of them and she got in such a state, holding it then wetting herself (then crying) we've all agreed to put her back in nappies and ease her into things.
We often encourage her to go bare bum round the house and on Monday we had a great day with lots of success (and lots of chocolate!) But obviously she can't go nude at nursery so they are keeping her in her nappies for a while. Do you think that's ok? I don't want her to have Best of Both (ie comfort of nappy when she needs it but all the excitement of the potty/chocolate).
I know it's early days - she's only 2.6 and we've only really been trying for a couple of weeks but I want to make sure we're heading down the right path.
Would really appreciate your advice
