Besides an actual baby, this emoji is also used when a long-prepared project or idea finally comes into the world. It feels like proudly showing off a precious creation, like "my baby."

This emoji stimulates protective instincts and symbolizes a being in need of unconditional love. That's why it's popular in internet memes where people compare themselves to a whining baby, like "Waaah, I'm baby [name]." This playfully reflects the desire to escape adult responsibilities for a moment.
