Blocks

Alan and I like to play with Cooper's blocks.

Cooper doesn't particularly seem to care:

But we can usually talk him into knocking down whatever we've built:

And sometimes we scream "Noooo!" like a village full of tiny people begging the giant not to destroy their home. And then he mimics us in a way that sounds like he's mocking the people of the town he's about to crush. It could get him into serious trouble in school as he knocks over someone's creation with a fake, high-pitched, whiny "Noooo!"
