People say kids can't do this and can't reach that. It never stopped me as a child, nor has it ever slowed down any of my kids.
There is no cabinet in my home that any of my kids didn't climb by opening the doors and using the shelves as a ladder. In fact, they have broken hinges off standing on the cabinet doors or using the handles to pull themselves up.
And they aren't hooligans, but if they want something on the top, they will get it.
Not saying the JBR was as independant and confident as mine are, but it wouldn't surprise me either.
