My little organizer

Ellie has taken to organizing and sorting as of late, and I find it fascinating to watch. I've read a little about it, and it's apparently an important milestone - it uses a part of their brain that is important later for math and problem solving. Who knew? These fun little quirks/milestones simply amaze me. I could sit and just WATCH her for hours. You can see the wheels turning and when she figures out something new the look on her face is priceless. A couple of videos below.
