Babies are weird/clever

Gosling turned 10months earlier in December, and has just recently discovered how to roll. Or should I say re-discovered. She originally figured it out at about 4 or 5 months (I think thats right... I'm not sure of exact dates), but she kept on banging her head on the floor when she did it, so she gave up. Seriously. She didn't roll for over 5 months, even though she knew how.

Recently, she somehow discovered that she would not bang her head if she rolled on a bed. Oh how she loved that discovery. The second I lay her down, she rolls over and tries to escape. And she laughs as she's doing it. Her other recent discovery that she can drag herself forward (no crawling yet, just slugging) makes things even more interesting, as she can be halfway across the bed in the time it takes me to grab a new shirt for her.

But.

She knows that she can't roll over on the floor. She lies there and cries because she knows she can't go anywhere. If I roll her over she's off like a flash, slugging her way across the room, but she will not do it herself.

This is where the clever/weird part comes into play. Its clever that she recognises the difference between bed and floor, that she can roll on the bed with no consequences, but its weird that she won't roll from her back to her front on the floor... even though that wouldn't hurt her, and she does occasionally try to roll onto her back on the floor, banging her head and ending up screaming.

I wish I could get into her head and figure out her thought process.
