Just talking to boy #1 and he thought you put the kebab stick in the pitta bread when you ate it. On the weekend, thing 1 decided that goldfish were actually called honey fish and then the others started calling them honey fish. They're all doing well at school but you've got to worry.
all families have their own words for stuff so I wouldn't worry about the honey fish. And if #1 didn't know about kebab sticks it's presumably because you hadn't told him before; now you have and now he knows.
They are all being children as they should be; funny and cute. Kids do have a way of making up words or making up names for things. I think they are adorable.
