Ds2 (3.9) has been dry at night for a while, with the odd accident. He still naps in the afternoon but has been dry then for many months, with no accidents.
The last two nights he has woken up sodden at about 1am both nights, and also this afternoon after his nap. An hour later he need to pee again and did so abundantly, despite having drunk nothing.
His poos are quite soft too.
I am not hugely worried - there are no other sympoms, no pain, appetite fine. I just wonder if anyone has any suggestions as to what could have suddenly caused this.
