Yeah, kids should totally be able to sit in those seats, which is why extending the netting makes so much more sense than nonsense like banning kids from key areas of the park, or requiring them to wear helmets. For a game that desperately needs more kids to become fans, shunting them away from the good spots just because some adults can't fathom the idea of seeing a game through some netting is pretty ridiculous and counter-intuitive. Extended nets lets everyone enjoy the game with massively reduced risk of getting clobbered by a ball or a broken bat, which is a legit risk for ANYONE sitting in those seats, regardless of age. People are getting hurt on the regular this way, so to act like removing kids from the equation significant reduces the risks or the injuries is faulty.
