Saw another case where a baby supposedly died from being shaken. Maybe it would save lives to do public-service ads on TV and radio stating what seems so obvious: Hey, never shake a baby, because you could kill it. But the obvious often fails to register. Witness Britney Spears driving with her baby in her lap. And while we’re at it, add a mention that, oh, put a baby on its back, not on its stomach. Cases of sudden-infant death syndrome dropped after this recommendation got out to more parents.
