Congrats on your new family member! He's adorable! Next time you're at Walmart, go to the sports section, and buy a CASE of tennis balls...trust me, you'll need the whole case. ;0)
We play "hide the ball" games all the time. We put them in drawers, pockets, in cabinets, under blankets, anywhere, and our girl finds them. Just amazing to watch.
