Sofia Sits herself up from her tummy

I don't have a picture or video of it, but Sofia sat herself up from being on her tummy ALL BY HERSELF!! WOO-HOO!!!! We were a little worried that she wasn't doing this yet, so I made an appointment at the pediatrician for Thursday. Of course, 2 days before the appointment she does it!! I guess that's just murphy's law! She's growing up :o)
