Those two blurs are Elizabeth and Helen going down a giant, inflatable slide at a friend's birthday party. Helen wasn't too sure about climbing all the way up to the top, but Elizabeth loved it and went several times. I guess that's the difference between a 4-year-old and a 3-year-old.
If my kids had their way, each day would involve a dance or gymnastics class, reading at the library, and a trip to the playground. Ah, if I had no other obligations!
