3 year old has been out of nappies for about a year through the day, with the occasional accident, normally when he doesn't want to miss out on something but otherwise fine. He's been wearing night time pull ups but literally never did a wee through the night so we thought it was pointless and decided to stop using them. He's happy with that and choosing not to have one (I tend to ask if he wants one or not). That's been the case for maybe 2 weeks. But now he's wetting the bed.
It's maybe every few nights, and I think it's happening just as he's waking up rather than the middle of the night. We make sure he goes to the toilet before he goes to bed.
I don't really want to put him back in pull ups, but I do find it odd he's gone from never peeing in the night while having them on to suddenly wetting the bed without them.
Any advice from people who've had similar?
