for educational purposes, and this is gonna sound a bit sus but I read it in this book - https://www.amazon.co.uk/Sound-Design-Expressive-Effects-Cinema/dp/0941188264, pitching down the sound of a baby crying can sound like sexual (female, stated in the book) groans. Here is a bit of an example https://www.youtube.com/watch?v=cr6eFl7hCiA .
I can't remember the exact reason they brought it up - but the book is a great read for anyone in sound design or films, etc.
