Night time Potty training regression

I don't really have any advice on how regression but i have read multiple times kids shouldn't be punished for for it when it comes to potty training, sorry I don't have any more advice x

I don't want you to read this and think we are being judgy, it's hard when it appears that it's regression due to behaviour and it's natural to want to consequence for that.
I wouldn't jump to that though, lots of time kids that take to it easily then can get bored of it and regress. Also, pooping with boys is a big one, give it some research, it is a big deal, can be scary or cause worry and not feel good and quite often in toddler boys they will be great qith weeing and struggle with the poops. It's interesting to read about :)
Because its in the night I would use undies or Pull ups and wake him in the night as a reminder, this is what I have done in the past. If he has an accident in the day he is old enough to not clean it on his own but old enough to help. It encourages them to think about their body and go tpulet rather then sit and continue playing and also take responsibility for it.. but not as a punishment.. 'oops, you didn't make the potty, we will have to clean this up".

He’s likely not doing it on purpose and even if he is he’s very little and not being ‘naughty’. My 3 year old has been dry in the day since he was 2yrs 3 months, most of the time he’s dry at night but he still wears nappy pants and he’s sometimes wet. He mostly gets up for a wee. I wouldn’t punish him for that. They’ll get there in the end.

I agree with the others, don't punish a toddler for having potty accidents.

Maybe if you woke him up during the night and sat him on the toilet he wouldn't wake up wet. As usually if u wake kids and take them to the toilet they usually do need to go, sometimes they don't and use pull ups so that if they do have an accident you don't end up too frustrated. As toilet training is about understanding our kids needs. But I have seen us as parents struggle more with it than kids. As we struggle with how many accidents we have to clean up and don't understand why kids can't just go toilet and not have an accident. But kids don't do it on purpose, they feel embarrassed by what has happened too. But they don't have knowhow or solution of what to do. And pooping during the night his stomach might not feel too good? Or he might be avoiding pooping on the toilet during the day which is why it happens at night? I cant really say. As you know your son best. So you would know what way would be best to go forward. You also know how best u can explain things to him as every child is different.

Night time dryness occurs because of a hormone being produced. This often doesn't happen until much later (Dr's will not discuss helping a child get dry at night until they are over 7).
Just because he was dry for a while at 2, doesn't mean that he will continue being dry, I have also experienced this.

Please don't tell him he is bad or naughty, and please don't punish him because he is not doing anything wrong. It is not something he can control. It would be the same as punishing someone for snoring, it is not something they can control.
