I don't think I've met a single parent who has taken their eyes off their children for ten or fifteen minutes. I've watched parents engaged in conversation at the park or looking at their phones while their children play out of their line of sight. How long does it take to scratch a lottery ticket? Five seconds?
(Though we've never met)
Waves. Over here. My son is on the spectrum. I would say until he was over 10 years old, maybe a little older, except when he was in the care of another adult, I never took my eyes off my son for 10 or 15 minutes in a public place or out of house. Ever. Ask my family, who delighted in making fun of me for being a helicopter parent when my son was small.
Also, please don't discount those few seconds of looking away. That's all it takes to lose a child. Because I, a helicopter mom, lost my son in the blink of an eye, LESS THAN 5 SECONDS, when an obstacle came between us and cut off my line of sight. I wasn't on my phone. We came upon a wide pole and he went one way around it, and I went the other, and when I got to the other side, he was gone. It took less than 5 seconds to pass the pole.
Something similar happened to my mum, my coworker, and a few other parents I know who lost their child in mere seconds, too. My coworker turned her head for all the time it took to pick up a sandwich and turn back, touching off a two hour ordeal of looking for her friend's little boy, who she was supposed to be watching. We're not talking fishing around in a cooler. It was sitting right beside her. She turned, picked it up, looked back & he was gone.
Unless it happens to them, no one has any idea how it feels, or that it's even possible, to turn your head away and then back in mere seconds, only to discover within those few seconds, your kid has vanished. So seconds count.
