My DS has never used a potty and for a long time would go hysterical if we tried to get him to sit on the potty or loo. In the end DH got him to sit on his Thomas seat fully clothed while it was on a stool. Once he realised he couldn't fall in he agreed to sit on it on the toilet, but I waited until he was nearly 3 1/2. In the end we decided to go for broke and he was clean and dry in 4 days, but we had to ditch the pull ups because he would just wee in them as if they were a nappy. There's no point in banging your head off a brick wall if she's not ready. Just ignore the other supermums who say their kids were potty trained by 2 or whatever. They all get there in the end, and for us waiting until he was ready made it a completely painless experience. Just make potty training a non issue for a couple of months. Besides, at pre-school they're only there for about 3 hours anyway, at my son's pre-school they're totally relaxed about nappies.
