Yes they are, but you're leaving out the most important point here. It's content SPECIFICALLY designed for babies. The onus is on the producer - whether it's toys, videos, ads - for us to have some regulation saying x is ok but not y.

By your method of thinking...let's just make everything OK for babies and let the parents decide.

That makes no sense...it's why society has laws (Why can't I go buy a bazooka in Europe? Because there are laws).
