@Lucy hopefully hun 😭😭
Have you had a look into the Eric Website? https://eric.org.uk/potty-training/ It has loads of help tips and resources into potty training. I found it useful potty training my son. Alongside bribery (chocolate buttons for every wee/poo done on the potty)
I am in the same boat, we tried all over the 6 weeks holidays but he just won’t do it. If he isn’t wearing clothes he uses the toilet/ potty absolutely fine but as soon as he has pants on he just wets himself 😞. I am trying to just leave him and not put too much pressure on him and hopefully he will see the other kids at school doing it and will want to do the same!
