My ds talks constantly too, even in his sleep!

Instead of having imaginary friends, he becomes other characters. One of them has an american accent and another an australian one. I have no idea where he picked this up! I am a cockney with a very distinct London accent and he has a Strong regional northern accent, as he has grown up in the north of England. However he can switch to London easily and is very convincing, especially as he uses lots of rhyming slang that he has learnt from his grandad.

He is fascinated with accents, dialects and languages. He even corrects my speech if I use my local dialect.
