There are actually two distinct ways to use the baby emoji. The first way is when you are actually talking about babies, either your own or another persons. A good way to use this emoji therefore is to use it when you have just received news that you or someone else is expecting. Drop this in a message with some accompanying text and you have a recipe for hype on your hands. Example: guess what I'm expecting 👶 

The second way to use the baby symbol emoji? When you want to throw some serious shade in someone’s direction. Sending a baby could suggest that the recipient is being whiny or just downright childish. An example of such a message would be: stop acting like such a big 👶
