We started off with teaching our 2.5 yr old to do wees on the toilet and giving him a sticker to put on a chart that I made on the computer.
It was VERY slow progress and I wondered if I was doing something wrong - especially hearing of 18 month olds that were "toilet trained"
There was a LOT of backwards forwards progression, but I stuck to the sticker reward system and then when DS was telling me he needed to do a wee, he would take me to the toilet to watch and verbal praise became all he needed.
Then we moved on to pull-ups.
I felt like they were expensive nappies, so went back to nappies for a while and helped him whenever he needed to go.
At 3 yrs he started to go to the toilet and take his nappy off, sit on the toilet and do a wee all by himself. So back to pull-ups.
Now he is 3 yrs, 2months and can go all night with undies on - YAYYYY!
He still "forgets" every now and then, but if he has undies on with no shorts, he's okay.
I think toilet training is just like learning to walk - starts with standing, then hanging on to furniture, then a few steps - and then RUNNING!
I felt a lot of pressure from relatives to have our child toilet trained by the age of 2, especially bu my Mother who says I was toilet trained at 12months - yeah right!
In the end I decided that it would be best to wait until he was clearly "ready" - ie able to pull his own pants on and off, otherwise, it seemed pointless for him to know how to do a wee on the toilet.

JMO.
I'm sure you will have a great time with toilet training - it is so cute
