Dalton got a pack of 25 cheap plastic balls for Christmas. We've been having lots of fun with them lately. In addition to the activities below, we've taken them in the bathtub and pool.
Indoor Cricket. We only have one bat, so one of them uses a wooden spoon. Also, this is more like croquet than cricket.Crib Toys.
And in our blow-up pool. It almost works like a ball pit. Almost.
