This thing is simply awesome. We use it about 5 minutes a day and Baby D LOVES it. He's a natural bouncer (thanks to Dad teaching him how to jump up while standing on your lap). A plus - his pediatrician gave the ok for us to use it (moderately of course).
She also called him 'gigantic'. What? He weighs 21 pounds and is 28.5 inches long at 6 months... World: meet a breastfed baby.
