From what I've read it varies a lot.
Yes my little boy is. He’s only been potty trained for about a month I’d say. But I’d notice he was getting really uncomfortable of a night so I just bit the bullet. Put a puppy pad under his bottom sheet. And we had 2 dry nights and then he did have a couple of accidents. But what I’ve started to do now is set an alarm on my phone at say 11:30-12pm to get him to do a wee on the potty he still half asleep if not asleep and he does that and then he’s fine until he wakes up on the morning. He goes to bed between 7-8 and he goes for a wee before bed aswell. I totally didn’t expect him to be dry at night yet especially with only just potty training too! He will be 3 in April x
@Lauren my little boy will be 3 in April as well, but he isn't interested in the potty yet. Also, if I woke him up to go to the toilet, he would be awake all night. Does your little boy go back to sleep afterward?
We've had a couple of random dry nights but nothing fully. My niece is 4 and she's just started being dry at night
