I have an east London accent which is co ckney.

My hubby is posh English.

My kids have been brought up in Scotland so can do all three lol they float in and out depending on who they are talking to.

Extract from my five year old a week or so ago he was speaking in a posh voice.

'mum, I know how to take teeth out ! Punch someone in the gob'. Gob being very common so it sounded funny at the time....
