Walking with Jagger

Roman has been walking on the treadmill with Jagger since about 15 months, but I finally got around to getting it on tape. He used to walk longer but now he mostly stops after a minute or two, or leaves Jagger to walk by himself for 10-15 minutes while he plays nearby with his cars. Jagger thinks it's great and even knows when Roman makes the sign for "walk," and runs and jumps on the treadmill. Roman pats Jagger when they're finished and tries to say, "Good boy," or "Guuu baaa."
