DD1 is 2.11 and had been potty trained (wee and poo) very reliably for about 6 weeks before the arrival of dd2. She is still pretty good (no accidents at nursery) but we have on average one wee accident a day at the moment (sometimes none, never - so far - more) and it's pretty deliberate (she has good control, knows to ask etc).
I know this is to be expected but just wondering (1) how long it might go on for and (2) what the best approach is. We've been just saying, never mind, you just forgot, next time you do it in the potty...do we need to be sterner, or less stern? on the whole she has handled the new baby arriving pretty well - so this is a small thing in the larger scheme of things, just wondered about others' experience
