Ask HN: AirTag in my Kid's Backpack

So, I was just looking at AirTags for putting in my 4-year old's backpack. I'm not really going to do it but after seeing abduction movies, the thought certainly crossed my mind.

However, based on the following Apple page:

It seems like if an iPhone user abducts someone with an AirTag in their pocket, the abductor would get notified that an AirTag is traveling with them.

I guess it can't be used for this purpose??? Any thoughts or has anyone effectively used it for tracking their young kid?
