Well, we were 'advised' by MIL to take DS to the loo when we went to bed, but we used to wake him fully and he had to walk to the loo himself so that he was completely aware of what he was doing. It didn't keep him dry every night in any case.
I think if you put children on the toilet still asleep, they just wee in their sleep, the very thing you're trying to avoid; so you might just as well leave them in a nappy. Also, some children don't take kindly to being woken and can't get back to sleep, resulting in grumpiness next morning. I did ask DS if he wanted us to wake him and he said yes, but he was good at getting back to sleep! With hindsight I wouldn't do it again.
Flagging, if you wake your DS before he goes to the loo at 11pm, he may become conditioned to waking at that time and taking himself to the loo, but if he wakes as he is wetting, it's not working.
Dryness at night is developmental, and when their bodies are ready, it will happen. A hormone is produced in the brain which slows kidney function, resulting in less, more concentrated urine. The eventually full bladder sends signals to the brain that it needs to empty, and this wakes the child so that they can get up and go to the loo. You can help improve the volume that the childs bladder can hold by making sure they drink lots during the day. Tail drinks off before bed, no fizzy or caffeinated ones or blackcurrant, which can over stimulate the kidneys in some DC.
Some people prefer to continue with absorbent night pants, some would rather change lots of wet beds, it depends on what is easier for the family in general. Night wetting is so usual before the age of 7 that healthcare professionals won't do anything about it.
Hope this helps you all.
