Share your pregnancy reveal story!

How did you tell your immediate family that a baby was on the way? 
For my close friends I want to wait to do a gender reveal party to announce the pregnancy. 
I don't exactly know how to tell my immediate family: mom, grandmother, sister, and brother. It's hard because to them I AM the baby of the family, but I'm grown now and that is sometimes hard for them to understand.
