Our eldest daughter has evidently watched too much Peppa Pig - I'm Mummy Pig, my husband is Daddy Pig, my Dad is Grandpa Pig. The only one who seems to have escaped this is my Dad's girlfriend Jan. We were trying to encourage 'Nan Jan' but so far it's 'Jam Jam'. There's also an imaginary Doctor Brown Bear who we have to call for advice (actually NHS direct!) when our daughter is ill or hurts herself! Not sure whether to be worried about old square eyes here or not :-S
