These premature babies have made great progress in terms of growth and development. Here they enjoy their Baby Einstein toy, a clever musical concoction. When the babies get excited about the star with rotating lights above them, they kick the arches. The act of the kick causes the music and lights to continue to play, so the babies have non-stop fun. As you can see, Justine (left) and Lauren (right) are smiling and talking to the star. They both love this activity. Well, in one shot Justine is actually not so happy as she grabs on to Lauren's sleeve.
