DD (2.7) has been trained for months but it's all gone wrong recently. She seems to have lost the knack of taking herself to the potty when she needs to wee. She can go a long time between wees so at some point if you time it right and put her on the potty she will do a wee, but, for instance, I tried half an hour ago and nothing, then 10 minutes later she wet herself.
There have been loads of accidents recently, I guess when we've been less vigilant about making her sit on the potty, but a month ago you could totally rely on her doing it herself. Also, a couple of times when she's got upset (fallen over and hurt herself etc.) she's lost control and weed on me while I've been cuddling her.
Is this just a stage, could she have an infection that's affecting her sensitivity?
