You'd be surprised of how young a person is when they develop a fetish. My foot fetish developed when I was only 4. First it starts off as a mere curiosity (as infants are always exploring and curious about everything), then it unknowingly becomes an interest of theirs, and finally starts to solidify as a fetish when they're about 10 onward. This video also sheds some light on this topic:

I can see a scenario where you're reading to the kids while wearing striped fun socks, and one of them notices your toes moving back and forth like a worm, and them curiously grabbing or pinching your toes causes you to giggle while struggling to read. I'll admit that's cute because they'd be having a playful moment with you.
