I hate potty training!!!!!!

We started potty training a week ago with bare bums and he was doing fantastic so now we've introduced trousers no pants or just pants he keeps peeing without telling us he needs to go or doesnt attempt to get to the potty.

I've tried using a sticker method everytime he uses the potty but that hasnt worked.

Everywhere stinks of pee and now hes just stood and done it on the sofa so that's going to stink too. Losing the will to live and sick of everyone saying how easy potty training was for them 😭😭

Has anyone got any suggestions 🙏
