I agree with the others hun. There's no harm in giving it a shot. But if she doesn't seem to be ready, don't push it. Just go back to nappies and try later. Also, I think day care will really help in that area, as other kids will be using the toilet, and they will probably put your DD on the toilet before meals etc, even if she's not actually tting yet.

As a working mum, I find the Christmas holidays a good time to bite the bullet and go full time undies, especially seeing as it's so warm. So you might like to try it before she goes to day care, while you are with her every day. But no harm if she isn't ready, another few months won't hurt. GL hun, let us know how you go.
