i thought i'd update, we have had 3 outiings without a nappy over the last 3 days. only 1 accident and that was on the longest outing (2 1/2 hours) which was today. She did do a wee and a poo in the toilet at the place we visited, though, which i was really impressed with.
i find that she's been doing so much better since we cut out the nappies completely. this morning, she even told me while still cuddling in my bed with the nappy on, that she needed to go, so we took her pj's and nappy off and she ran to the potty.

we never really did sign language, but she often calls mummy and touches her crotch to tell me that she needs to go. that was before she started using the words.

and poo seems to confuse both of us as it's the same word for her favourite movie or having to go to the potty
