I found a great book in Kmart called Toilet training for boys and it has a flush button included. It talks about going to the toilet ans says that sometimes accidents happen.

GS took this with him everytime he went and we read through it. As he relaxed we had success and within a couple days he was hardly having any accidents. A nappy was still used at night but he soom learnt to get up and go if he needed to.

DD also used either a smartie or a small animal toy as a reward. GS had turned 4 before he was interested. We have a seat that fits under the toilet seat and a low but wide stool for climbing on. If you visit parents often either take the seat with you or get them to get one.
