So you know how when you go to knock on someone's door you ball up your fingers into a fist? Well, picture an adorable one and a half year old doing his fingers like this and then "knocking" on your arm. Instead of just using one finger to tap/poke us, this is what my little guy does to get our attention. "Knocks" on us. He just started doing this the past few days and it is just way TOO cute!
