DS just made up a knock knock joke all by himself!
We opened some xmas crackers we found and read out all the knock knock jokes inside. Ds had never heard them before, then he turned round and said
'knock knock' 'who's there?' 'Doctor' 'Doctor who' and he just grinned!
I know its an old joke, but DS has never heard it before and just made it up all himself.
He is just 3. Its the cleverest thing he's done... There must be some kind of gifted and talented register to put him on
