I got 3 kids. My oldest son is almost 6, after our third came this spring he has had a complete regression when it comes to using the bathroom. He potty trained very easily, was completely fine when his first sister was born and only had resonable accidents like being sick.
Everyday he pisses his pants now, he'll piss himself in public, he'll piss himself at school and now he's pissing on his bed room floor at night. We took him to the doctor and they ruled out any sort of constipation or physical problem. We know he can do it, he did fine for 4 years. We tried a reward system where if he doesn't piss his pants for 14 days he will get a new lego set. He has just given up and isnt even trying for the set anymore. I've started taking toys away for every time he has an accident, he doesn't care. The only time he won't piss his pants is if we are at the zoo or something similar and i tell him "if you have accident we are going home immediately" this is the only time he won't have an accident.
People have suggested its an attention thing but i involve him in everything i do, I'm teaching him to ride a bike, swim and he helps with cooking and chores.

Im at my wits end here. I'm ready to just start beating him if he continues this. I'm tired of cleaning up piss and i feel like I've exhausted all the nice options. Any suggestions before I start giving my son tje belt?

kid quite possibly just fucking hates school, sounds like a (you) problem for pawning him off to retards for indoctrination camp.

Have you tried shunning? I think you are supposed to point out all the things he can do because he is older but that probably isn’t going to get results. Idk, don’t listen to me. Hang in there though. You can do nothing about it and he’s still going to knock it off, eventually.

Threaten to send him to a Christian private school if he doesn't man up.

Serious answer: might be sibling rivalry wrt the youngest in the family. It's a documented phenomenon.

In the meantime, consider pull-ups. I think they do make those in L or XL sizes for instances like your son.

Do you hold him accountable for his actions? Like make him wash and dry his p'd on clothes or scrub his mattress after he wets the bed? If not try that. Just be consistent with it. Make him feel embarrassed for actions desu. Tell him all the kids at school are going to make fun of him if he keeps doing it. That's what I told my kid before he went to a camping field trip. One of the kids in his cabin wet the bed and all the other little shits made fun of him the whole trip. I told my son you see? That could've been you.

Actually quite common - any child-rearing book should have advice. What's going on in his head (though he doesn't have to words to explain it) is "There's a new baby. Parents love the baby. I'll become a baby again so they'll love me"

Kids are so retarded.

>People have suggested its an attention thing
That was my thought too. New babies get so much attention that older children feel ignored and frightened that you don't care about them any more. Punishing him won't help: he would rather be punished and noticed than not punished and ignored.

It may possibly also be a stress thing rather than a direct means of attention seeking - and threatening him with horrible punishments is definitely not going to make him any less stressed.

You need to find ways to reassure him, not punish him.

you're probably abusing him or something
