Sorry, babies. Science says it really will hurt your brain. Pro tip:

Instead of allowing infants to watch videos or screens, parents should talk to them and encourage independent play, said the first guidelines on the subject issued in more than a decade by the American Academy of Pediatrics.

Which makes me wonder: Is the problem the screen-watching itself, or does lots of screen-watching before the age of two simply correlate strongly with having parents who can't, won't, or don't even know they should help a child's brain develop? I shall ask our parenting issues editor about this later today.
