DS, who was 3 in June, has been toilet trained since about february and dry through the night pretty much since then too and so we stopped daytime and nighttime nappies at about teh same time and he's been great. I think i can count on one had the number of times I've had to change the bedding because of accidents.
However, the last 3 mornings when i've gone into him, he's wet the bed! When he wakes up, he doesn't get out of bed (never has done) he just talks to himself and I then hear him and go in. I've stressed to him that when he wakes, if he feels the need to do a wee then he must call out for me very loudly but he hasn't ever done that. As I said, up til now, it's not been a problem and quite often he'll have been up 30 mins or so before going to do a wee.
Any advice please on what to do next? Nothing has changed in his diet/drinking habits these last few days. His bedtime routine is still the same. What's going wrong?
