baby jumping jacks

The boys needed to let some energy out before bed. Steven told them to do jumping jacks. Tyler was in the corner and rushed over and started flapping his arms bouncing up and down on his knees right along with them. He continued to do it even while I went to go get my camera. I know maybe you had to be there to truely appreciate it, but it was awesome:) He has done it since too. he's 10 months old.
