Not only is Savannah still lifting her head - she's looking up (I was sitting in front of her instead of laying on the floor taking the picture). Her legs are still kicking like crazy but no movements yet. And almost if not all rolling over by herself is in the mornings in her crib - we find her on her side many mornings.
She has a lot more fun after tummy time when I start rolling her from tummy to back. Granted, there are a lot of tickles and face making with it. :)
