DS1 was 3.5 when we were finally sucessful, lots of gentle encouragement before that but he wouldn't have a bar of it. He started with sitting as he was never was a big fan of the potty. Now at 4.5 he's majority of the time standing.

DS2 is just over 2.5 and sees DS1 and is doing a lot of pretending. I would love to get things moving for him but not too sure about his readiness yet. I had a day without nappies the other week and it was enough for now. Although this week during a nappy change he said he wanted to go do a wee and stood there for a few seconds aiming off our decking and he actually did wee!!!!! I was so excited for the somewhat sucess so much ealier than DS1. As soon as the weather is a little wamer here i will really get stuck into it.

Good luck with it
