Joerg, Ann, and Oli sent Carolyn a "jump-a-roo" when she was born... and we set it up a couple of weeks ago. She loved playing with the toys on it, but just learned how to jump in the past few days. Perhaps she grew that last 1/2 inch allowing her feet to touch the ground or perhaps the springs loosened up a bit from her sitting in it. Whatever the case, she loves the toy and spends quite a bit of time in it each day. The only problem is that I hate how big it is, so it hides out in the guest bedroom.
