It's not that it doesn't get discussed. It's just the way the biases work. People don't recognize the dangers because they're used to it. They place a bigger worry on other dangers that they aren't as familiar with or feels more scary. Most people don't even think about the dangers from pools or car accidents, or overestimate how safe it is despite their lack of knowledge. Many parents put their kid in a car seat but fail to secure the child or seat according to the instructions (usually straps too loose or in the wrong location). Or they think that just because they are sitting near the pool passively watching that they could save them if something does happen despite the fact they have no training. Yet the same people will talk and worry relentlessly about a school shooting despite the stats showing that schools are one of the least likely places that children are to be shot (more likely at a private residence or in the general public, more likely in a one-off event than a mass shooting), but don't bother discussing if there are firearms in the house and if they're locked up. It all comes down to bias.
