My little one is 16 months and has just discovered the joys of playing with a ball. We got him a small inflatable ball which does not hurt at all when it hits you and he loves it! When we throw it to him, it usually bounces off his belly or his arms since his reflexes are still a bit slow to catch it. But if we roll it to him slowly, he scoops it up and tries to throw it back. Sometimes as he puts his hands over his head to throw, the ball falls behind him and he stands there perplexed. It is ridiculously cute. Other times he just bats it in our direction. It doesn’t really matter what he does, it is all delightful. He laughs and we laugh. Thank goodness for simple toys like balls. No bells, no whistles, just giggles and fun.
