Hi bobbikay, my lot never used a potty they all went straight to the toilet, I had a seat that has a built in kids seat as well as an adult one, best thing ever as they felt grown up using the same seat as everyone else, you get slow closing ones now. I learnt after my first to wait until they are ready, I spent weeks with the eldest trying to train her. With the twins I tried them at 2 and half didn.t work, left it for 6 months and was done in a day. The next set of twins were 3 before they were ready, one kept taking off her nappy when it was wet and the other wanted to be like his brothers and use the toilet, again they were done in a day. I just put pants on them and let them run around coulple of mishaps, but they didn't like the feeling of wet pants, not a fan of pull ups, they feel like nappies. Sounds like he is nearly there, I'd leave him for a few more months and then try again. Good luck you will get there, just go at his pace.
