I hope the answer is yes!
I started potty training DD (2.4) about a month ago and she got the hang of it pretty quickly. She's happy enough on the loo or the potty, can take herself off to the potty and dry herself, and as of last week has been dry at night which was a pleasant surprise.
However, the last few days we've gone from no accidents at all (bar one where we were waiting in a very long queue for a public loo, which was kind of understandable) to having lots of 'little accidents': she'll wet herself slightly, announce she needs the loo and manage to hold the rest in until she gets there. This didn't happen a week ago, where she'd be completely dry once she got to the loo. For some reason this seems to be much worse at home (think four changes of knickers during a day at home versus none on a day out) and on a couple of occasions she didn't seem to realise anything had happened.
She doesn't seem distressed at all and has no issues with using the potty: the only thing she hates is if I remind her to go (usually the response is "I KNOW I don't need the loo!"). Is the regression a normal thing? My washing machine has been lulled into a false sense of security... but I'm not keen to go back to nappies as this would be really confusing for her.
