tethersend, take no notice of the ils, do what you feel is right for your dd.
However, you could introduce a potty if you think she is willing, get her to sit on it for a couple of minutes, and praise for staying on it, make no comment if she gets off. Praise if she does something, but again no comment if not. Put nappy back on. We are not talking training in the way most people mean i.e. removing nappies altogether and the child has to use potty or loo. The child doesn't need to have bowel or bladder control. It is a gentle method of accustoming a child to a potty, and allowing it to be part of the daily routine. The number of times the child sits during the day can be gradually increased, after meals for example, or at nappy change times. There is no pressure on the child and you have the back-up of nappies. At this age there will be no confusion about using potty and wearing nappies. This can go on for months before you or your dd finally decide the time is right for the more intensive training. The child also gets used to seeing what they have produced in the potty, and are not afraid of it. Some older children who have never seen a poo in a potty are horrified, because it looks nothing like the misshapen mess in their nappy, and refuse point blank to do it again, resulting in with-holding/constipation, or lots of soiled pants. And some can't bear the feeling of something 'dropping away' from them, so getting used to that is useful.
I can't help wondering why parents who suddenly produce a potty and expect their child to sit on this alien object and deliver the goods at 2.5 - 3yrs because this is when they think it should be done, are surprised and angry when the child flatly refuses. The child needs to be confident about the potty before they can tackle no nappies as well.
Sorry for the long post, I just wanted to present a different outlook on potty training which a lot of people are not aware is an option.
