We were in the car today heading to the park, and Libby started sqealing with laughter. I turned around to see this. The windows were down, the air was cool, and she was loving it.
On a side note, you may notice that she is still rear facing and in a car seat with a 5-point harness. She can safely rear face in her car seat until she reaches 33lb. and can forward face in a 5-point harness until 80 lb (there are also height limits on those, but she is unlikely to reach the height before weight). Please check out the two videos linked above (especially if you have young children) to see why that is so important to her safety.
You will have to excuse the bad quality of this picture. I wanted to post it anyway because of the look on her face. Sheer joy!
