If you don't already; spend some time watching Rick Beato's content on YouTube. Lot's of great stuff but in a particular early video is Rick's amazing son Dylan and his ability to discern complex pitches, notes and chords. It's four years old. In a later video, Rick explains that the earlier you can recognize notes, the more likely you are to have perfect pitch. The older you get, no matter how hard you try, you'll never have perfect pitch but you can get really good at it.

I think to this thread, it's these amzing kids not really have an impedement to learning. By the time I picked up guitar, I was in my teens with nearly no previous musical training so there was never going to be a Jeff that was going to have these kinds of superpowers. At best, I good, solid ear for stuff.
