I'm like the parent, I just can't see the common IR LEDs with the naked eye, not even faintly, not even in pitch darkness with the led 1cm from my eye. I think you just have a skill that we don't. Or maybe you just have IR leds with shorter wavelengths...

Hmm, this thread would suggest that many people can see it:

Security cameras with IR leds are pretty bright to me. I can easily tell when the IR leds are on. Have you noticed anything like that?
