Here's a video of my niece, Danika, opening a gift from us for Christmas. (From 00:35 to 00:53 is the funny moment.) Ugh, I hate having to convert to Movie Maker to brighten this... it now has spots and lower quality. I don't know why it does that, sorry.
In this video Danika's playing with the Playskool Busy Ball Popper we got her for Christmas. (I think what she does at 00:30 is so sweet, like she's trying to express that she likes it. Just get it to 00:27 and watch, after she does it, I go "Ohhh...", like "Aww.")
