Thanks for the tips everyone!

My DD wasnt ready for TT till she was about 3 so im not going to rush it this time either unless he seems ready. Might wait till the weather warms up a bit and give it a go - i think i might even wait unitl after xmas when i know i can stay home for a few days, at least until he gets the gist of things.

What i would suggest is when you are ready let your DS run around nappyless so he can start to feel what it's like to wet. So that he can then relate the feeling of needing to go, to wetting himself and then knowing that the feeling means to run to the toilet. That's how it worked with us. It took us forever to have DS1 finally do a wee on the toilet.
I'll definitely give that a try EJ. Thanks!

He learnt sitting down and I taught him to hold his 'tonky' down so that the wee went into the toilet and not all over the seat/floor/wall!
That's my main concern!! LOL
