Claire is a great sleeper and typically sleeps at all the same times as Addison plus some. On one rare occasion Addison took a three hour nap and Claire was done after 2.5 hours. During those 30 minutes of mom and Claire time we decided to have a photo shoot. I didn't have to take identical pictures of Addison and I could make some effort to actually get a photo of Claire smiling.
In case you are interested in some comparison - the right is Addison at 6.5 months and the left is Claire at 6.5 months. They really look less and less alike the older they get.
