Ds, nearly 6, has not had an accident in at least two years, today had a complete loss of control. Just as we arrived home from school, literally on our driveway he said "Mummy I need to do a wee", and couldn't even hold on until we got into the house, or get himself out to pee in a corner, but just let everything go at once. He was not particularly happy (but not hugely bothered either, maybe because I didn't make a fuss), but what worries me is that he said he had absolutely no warning or feeling that he needed to go before he told me.
The only time I've ever come across this before is when the same thing happened to me in Sainsbury's three weeks after dd was born. But then it was sort of understandable! What's going on with ds?
