a busy little girl

Our new baby is often a busy little girl. The last couple days, I have really felt her a lot because I've been resting. The thing that is most interesting to me is when she moves her hand across. (at least that's my best guess about what it is) Rather than the more general movements that I often feel, this is a specific small spot that quickly moves across from one side to the other. When she makes this movement, it almost makes me jump because it's so different.
