Child endangerment these days also includes letting a couple of three year old boys duke it out until they both just sit down on the ground and cry, neither the victor in the match, but equal in their inability to inflict any bodily harm at their ages.
Funny how 35 years later they are still the best of friends. Of course back then, in the days before vaccines, when one smiled, took off his shirt, showed off and bragged, "I have mickenpops" while jumping into the backyard pool that had just been erected, you either quarantined the entire neighborhood or you just let them all go swimming, and they all lived to tell about it, while being told to go get shingles shots. Yes, we endanger them by letting them skin their knees by falling off the bike, and everything.
