Here's what we know:
* Baby language is instinctive: Parents and caregivers naturally use higher pitched voices, simpler words, and more repetition when talking to babies. This is thought to be driven by instinct and a desire to engage with the little one.
* It's not a single language: There's no standardized set of words or phrases used in baby language. Instead, it's a collection of features that adults use to communicate with babies.
* It's culturally influenced: While some aspects are universal, specific expressions and sounds can vary from culture to culture.
* It helps babies learn: Baby language helps infants develop language skills by exposing them to sounds, rhythms, and the basic building blocks of communication.
So, while there's no single inventor, we can thank our evolutionary instincts and the desire to connect with our little ones for the creation of this universal language!
