She's a carrier

Madeline loves to carry stuff. And the more of it, the better. Sometimes she'll spend 20 minutes just trying to walk across the room while holding two things in the same hand - not a single whine or whimper as the first object slips from her grasp when the second is introduced. She just quietly works to hold both items, and when she has them she begins to walk, until one or both invariably falls from her hands.

She has even been known to walk with both hands full and another object in her mouth. Who knows where she's taking all this stuff, because she never makes it to a destination. The goal just seems to be holding several things and walking at the same time.

It's obvious that Madeline is fine-tuning her manual dexterity and balance, and at the same time she's learning about the physical nature of objects - how they feel and how they interact with the environment. I think it's pretty fun to watch, especially during those few precious moments when she succeeds - to see how happy she is when she finally manages a few steps with her little hands full of toys.
