Look who's sitting up!  She did it about 2 weeks ago!  She pretty much has it mastered.  She falls every once in a while.  She's doing so good.  She doesn't roll over.  The doc said it's no big deal since she's sitting up.  He says she's getting all of her muscles worked that way.  I wish I would of known that with Baine.  I always worried since he never did anything but sit up and then walk.  I hope she crawls.  We'll see!
