At just over 5 months old, Amelia is sitting up! She first sat up on Monday 5/6/13. Incredible that she is already old enough to do that! Barrett was getting her out of her pack n play and tried sitting her up in there. Well it worked! She was amazed with herself! She was really laughing while trying to stay sitting up. She must be very proud of herself. We sure are! We aren't to the point where we will leave her unattended to sit up. We are still there to catch her as she tumbles over. As of today, she will last close to a minute or so at times before tumbling over. So much fun!
