Jael, I'm a midlander too! No snow here either.
Monimo, I've been told the key to successful potty training is to take your cues from the child and leave it until they are ready. DS did a wee in his potty when he was 13 months or so and we were so, so proud and smugly thought we'd have it cracked! But at 2.1 he still isn't ready apart from the latest development which is to tell us when he is damp. However, he just isn't ready I think as he refuses to admit when he's had a poo, never mind tell us before!
It'll happen when it happens. No one ever goes off to university in nappies do they?
