I got the idea to buy cups for the boys from another blog I read. I can't remember which one it was for the life of me. I wish I could so I could link to it. If your reading and this was your idea let us know!
They love this and so does Noah. He tries to stack them and then he loves to knock down the huge towers the big brothers make for him.
This was less than five dollars for all of them. The boys told me that they needed another big package of them. I think I can do that.
