Me again. Well, DD1 definitely is potty trained! She's had no accidents for a week now, and has really got to grips with it all. We've even managed fairly long car journeys (half an hour), church (an hour!) and trips out to the shops and the park etc. I'm so proud of her. She was quite anxious about pooing in the potty but always did it in the potty, she used to cry a lot, but now she just does it without me even noticing and asks for her bottom to be wiped!!
I have heard from nearly everyone that girls are easier than boys.
I have also heard that the 'going into a corner to do a poo' can be a sign they are ready. A friend recommended a book to me called (wait for it!) 'Everybody poos'. It's available from Amazon etc, about £5, and it's just quite funny, 'elephants do big poos, mice do little poos'. We bought it for DD, and talked a lot about how everybody poos, Granny, Nana, Mummy, Daddy etc. The other thing we did a lot of, which sounds gross but I'm sure it made a difference, was showing her her poo in her nappy after she'd done it and showing her me flushing it down the loo, and even sometimes showing her us doing a poo etc. Apparently they can get scared when they poo that they are losing a bit of their body or something, so in preparation for potty training, show them the poo and talk about it a bit.
Hope that helps.
