LOL Sheza, I know exactly what you mean. I had been freaked out about TT since Sam was born!
I say let him sit on it if he wants too definitley. Sam sits on hers and watchs TV
My SIL works at a daycare and she gave me the best advice ever. She just said that when they are ready it is easy. If its a struggle then they are probably not ready yet.
We tried with Sam a couple of times but she just wasn't interested even though she would tell us when she had done wees or poos in her nappy. She just didn't want to have anything to do with knickers, pottys or toilets!
She started Kindy in mid May and within 2 weeks TT'd! Totally took me by surprise, but the most amazing thing is how easy it was! There were a couple of accidents in the first few days but it has now been 3 weeks today and no accidents since. She takes herself off to go when she needs to and just calls out when she is done, and she will happily use the potty or toilet where ever we are

I am so glad I didn't push it and just waited till she decided she wanted to do it
