Bella's new thing is never, ever, under any circumstances saying 'yes' or 'no'.
"Do you want to go to softplay?"
"Would you like eggy bread for lunch?"
"Did you do a pee?"
"Did you finish all your porridge?"
It may not sound like much to you, but after eight hours of it...
On the plus side, Bella actually posed for this photograph and followed instruction. That's a first.
