why does my son do this? Please help!

[Palease]

My 3 year old has been potty trained since January this year. However in the last couple of months he just won’t go to the toilet for a pee, he waits so long that he wets himself but even then he doesn’t care! It’s not so much it all comes onto the floor but just wets his trousers and he carries on like nothings happened. I’ve given him treats every time he goes but he still won’t go. I see him jiggling trying to hold
the wee In and when I tell him to go to the toilet he says no!

Have you asked? At a time when he doesn’t actually need a wee.

Pick him up and put him on the loo.

My daughter did this. At one point she went 24 hours without a wee. She would hold until she literally could no longer hold it.

We solved ours after months of trying so incredibly easily. I put a recordable alarm on my iPad. I recorded myself saying "it's potty time!" I set the alarm for every 3 hours during the day.

When the alarm went off the first time to my amazement she went and sat on the potty and did a wee. We used the alarm at home and nursery for about a week. She never had a single accident from that day on.

He knows he needs to go but can’t be bothered! Be firm, “no” is not an option!

They wait until the last minute because what they are doing is more interesting. They can’t judge when they enter the danger zone.
It’s good to remind them at a time when they aren’t immersed in something. It’s easiest if it’s before an activity they want to do or before a meal or snack. The next thing doesn’t happen until they’ve visited the toilet.

He doesn't want to stop what he's doing. And he's 3....
I think you need to tell him (at the moment if he's saying no you're asking) "you look like you need the loo, we don't want wet pants again, come on now, sooner it's done the sooner you can get back to what you're doing".

If he does wet himself then a 'natural consequence' is that his play is interrupted, he 'helps' with the chore of cleaning up,

It's literally because he's having too much fun to stop what he's doing and go to the toilet, if he's doing the jiggle dance he is well aware he needs to go!
If he wets himself, make him totally responsible for it. Not in a bad way, but he takes his own wet clothes off, finds new clothes, puts them on himself, make this last as long as you can, and then gently tell him (or show him!) that it takes far less time to just go for a very quick wee!
Just say something along the lines of "ohhhh ... never mind, now we've got to stop play and sort ourselves out"

Don't be tempted to change him quickly yourself.
And no need to feel annoyed with him, at three, this will pass.

We have this a bit but if you say to him do you need the toilet he will say no 🤪

what I have had some success is saying firmly to him if we are out that I don’t have a change of clothes with me so if his pants/trousers get wet then that’s it they will be wet. Funnily enough he will then go to toilet!

Thanks everyone. I know, he’s just having too much fun and doesn’t want to have a wee. Well you’ve all made me realise I’m giving too much autonomy to him letting him choose when to go (tbf he was going when he needed for about 2 months after potty training). So yesterday and today I’ve been taking him every couple of hours and he’s had no accidents. He also seems really happy he’s had no accidents as he told daddy this when he came home.

Sometimes I just need someone to state the obvious - “take him to the toilet when he needs!”

@Toasticles This is a brilliant idea, I may pinch it for my own use !
