In case it helps, I found it really important not to chide or get cross or get stressed with my son when he had an accident and just to be calm - not saying you have, but mentioning just in case - I noticed some mums did get stressed with their children and this seemed to make it worse. I would keep it matter of fact and just say lets get you cleaned up. Early on I always kept a potty in the living room and from what I remember, I would offer the potty around meal times or if I noticed something about to happen. I kept a pull up nappy on him at night for a long while until it was obvious that he wasn't having any accidents - I didn't want the hassle of changing all the bedding and also not to put pressure on him.

Sometimes I would offer a book while he was on the potty to encourage him to stay if that was an issue.

Initially I always had a potty in the bathroom but this soon progressed to a trainer seat on the toilet and he got used to using this pretty quickly with me lifting him onto it and keeping him safe while he was there.

This may all be obvious, so just ignore if it is - but he adapted pretty well doing the above.

I don't know how tight funds are, but just trying to think outside the box and wondered if you had thought of getting a special coloured potty that he could choose? Or alternatively keep a small selection of board books next to one? Or also have a teddy or a male doll and get it to sit on a toy potty next to him?

I think if he was making messes outside the potty, I may see if getting the potty and making a point of clearing it up into it would help him associate the two - and of course a smile/ praise for when he does it on the potty itself. As he's a little older a star chart might possibly be a good idea too?

Hoping that something may be helpful. Take care.
