We were excited to get this as our 10 month old baby does everything but backflips when it's time for us to change her diaper. We really wanted to like it, and it worked the first few times, but after the novelty wore off she went right back to doing full 360 rolls during diaper time :( It doesn't physically restrain the baby from rolling (which is probably a good thing) and may work well for slightly less active/more easily amused babies, but even with the addition of new toys to the rings it...
