Does anyone have any suggestions on getting my nearly 3 year old to revert to correct pronunciation? She started speaking pretty early and extremely clearly, and is about 9 months ahead of her peers in vocabulary, grammar, sentences etc. I vaguely think it started with making up silly voices before Christmas, which was fun, but gradually progressed to a full time west country accent (and I'm pretty sure she's never met anyone with that accent), then when I started to gently correct it about a week ago it's now turned into dropping all her ts - again, I don't think she knows anyone who speaks like that. I'm concerned it will become such a habit that she won't go back to the correct version. Also her 15 month old sister is picking it up.
