And she’s off!

Every so often, I would put Abi flat on her back in her crib and leave her room.  I would then come back, and find that she was at an angle to the position in which I left her.  Yesterday, I put her flat down, about a forearm’s distance from my iPhone (used to play white noise).  Within a few hours, she was just 1-2 inches away from it.  

Well, the mystery was solved today.  Laying flat on her back, Abi maneuvers with her heels.  I saw her move about 1/4 a foot forward while laying on her back today – she just pushed with her heels.
