Hi Sam,

Not sure if this would be any help, but the answer to my toilet training problem was to buy one of those little seats with 2 steps that goes over the toilet. My daughter flatly refused to use a potty and this product was the answer to my problems because she liked to use the toilet mum and dad use but was scared of the big seat.
We bought it with her at Big W (I think it was about $35) and brought it home to put together with her. It comes as a flat pack but is very easy to put together. Chloe helped to assemble it and take it into the toilet. She thought it was great fun to be able to climb up the steps and sit down by herself.
Maybe your little man might like the idea of a ladder as boys generally love to go climbing!

Good Luck!
Ali
