Almost 4 and still not potty trained

Hello everyone 😞 my son will be 4 late June and he’s still in diapers.

We’ve tried everything to try and get him interested and he even had a couple of days where he would go all by himself, no problem! So I know he KNOWS how, he just refuses to. I’m due in 2 months with our third so I don’t want to push it when his life is about to experience a big change but I’m tired of all the comments I get about how he should already be potty trained.

His dad tries to show him and even his big sister tries to get him excited and nothing. He’s just so stubborn.

I don’t even know if I’m posting this for advice or just to vent a little but I’ve just been feeling like i could do more even though I’m trying everything.

Thanks for reading if you got this far!

I hope everyone has a good day
