I was planning to start in a couple of weeks anyway, but it looks like she's beaten me to it and has decided that's it, nappies are for babies. (typical DD!) She's nearly two and a half.
So, it's really taken me by surprise - we had a potty already, but no knickers at all. (I have them now).
I hope we're doing all the right things. I was going to read the little Gina Ford book and do it boot camp style. I had planned on using the coming bank holiday weekend to start, but this is a bit awkward now because DP and I are busy over the next few days so she'll be with babysitters and I'm sure they've got plans to take her out and about in this sunny weather this weekend.
I just hope she doesn't lose her momentum and enthusiasm! Any tips? She's not in nappies at home at all now apart from at night of course. We've had way more successes than accidents so far (maybe 10/2?). And she's OBSESSED with her new big girl knickers, so that's good.
I think she's slightly confused about poo though - she started going today in her pants so I whipped them off and put her on the potty, so we're calling that one a half success. Also, she took off a pooey nappy and gave it to Nana on the day this all started. "Here you go, Nana, I've done a poo."
So at the moment I'm still putting her in a nappy when we go out. I hope this isn's detrimental. The Gina book is literally in the post. DD couldn't even wait until that had turned up. 
Any advice very welcome. Thanks!
