Maddie is learning to walk.

I left Maddie in her playpen and the next thing I see was that she let go of holding onto the railing and walk two steps. Wow, she is about to walk pretty soon. She is not afraid letting go in her playpen because she knows that it doesn't hurt when she fall. Not like the crib she always take caution before doing things. Experience learned. Goodluck baby Maddie.
