My camera hasn't made it out much lately, but I had to catch this the other day. Benjamin really loves the jumparoo much more than Jonathan ever like the exersaucer, but I couldn't believe he was able to go to sleep like this.
Notice how he holds on for dear life when he starts jumping.
And Jonathan's mark wasn't absent from this scene. You can't see the line of cars all the way around the other side of the base.
