The parents are nuts. A baby should not be that close to the field between the baselines. And, nice catch by the lady.
I don't get why people bring babies to such events. The baby can't appreciate it. It certainly can't enhance the experience for the adults. And I question the wisdom of bringing a baby into the midst of tens of thousands of disease vectors.
But that's just me. If any Freepers like that sort of thing, who am I to judge?
