This has happened a few times over the last week, but only in the bathroom where the as yet unused potty lives.
My normally cheerful DD (21 months) has recently started saying 'poo poo', taking all her clothes off, including her nappy, and pretty much wailing. She then does a wee while still crying, and only stops when we've cleaned her (and the floor) up.
The GP says she hasn't got a UTI as she's quite happy to wee in her nappy, there's no redness around her bum and she seems quite comfortable there normally.
We think she's too young for potty training so we haven't pressured her to use the potty at all, we just play at taking turns at sitting on it at the moment in order to get her used to it. Also it makes a great bath toy! I've tried suggesting she sits on the potty when she gets upset and she refuses vociferously, in fact it makes her more upset. Once I even suggested the toilet (in desperation) but that met with the same response.
I've asked her nursery if she's done anything like this there, but they say no. They haven't suggested she's ready for potty training either.
What the heck is going on?!
