He's started calling Mrs H 'Diddy'. He says my name, I'm Baba -
easy to say for a two year old. He knows she's really called Granny, but never says it. He calls "Diddy!" instead.
I reckon it's because the 'd' sound is easier for him to say than the 'gr' sound. That only partly satisfied my wife "I know I'm not tall, but I don't want to end up being called Diddy. I'm going to have a word with him!"
She asked the little feller "Am I Diddy?"
"No", he said emphatically.
(But she is a little bit diddy though!)
