The jumperoo returned to our living room this weekend. It is so interesting to watch Evelyn in it - she loves it, and instantly figured out how all the toys worked. It took weeks for us to get Max to notice they were there, and even longer for him to start moving things around. E was in the thing for about 15 seconds before she started spinning and pulling on the various activities.
Checking out all the cool stuff going on all around her. She somehow intuited that there was more after we moved her around about 60 degrees.
Of course, moving her to vertical only makes Evelyn more interesting to Max!
