Mr 4 has been fully toilet trained for a year and half now, he's only had 2 accidents in total and has never wet his bed at night.
For the past week he's wet his undies once in the shops ( apparently he was holding and had 'forgotten' to pee until it's too late, made a run for the toilet and didn't quite make it there ) and he's wet his bed 4 times at night.
Just then I heard him opening the toilet door, so I went to check on him and he was there standing in the dark (which he absolutely hates) with his pants on and peeing on the floor.
I am a bit puzzled as to what's going on.
Any ideas anyone?
