Elisabeth Rolled Over, Again!

Elisabeth rolled over from her back to her tummy today for the very first time!  I had laid her on her mat upstairs and walked away for a moment to put something in Abbie's room and when I came back she was on her tummy.  Abbie said she just rolled over!  I couldn't believe it!  I think she is rolling even earlier than Carter did.  I guess she is very motivated to keep up with her older brother and sister.  I wonder if this means she will be an early crawler and walker.  I bet sleeping on her tummy is in the not too distant future!
