She's also sitting up on her own & seems to enjoy getting up into the new perspective of sitting & then once there looking around a bit & just enjoying the view. She's a very aware & attentive baby.. and while she enjoys getting mobile, she won't yet scoot around just for the sake of action: as long as someone is near she is content to play where she is.
If we leave the room though, she follows, whining & muttering if she doesn't see us right away.
