Anyone knows a cool exciting way to tell our parents we having a baby ?

Emily • I am 22 ,I`ve been raising my husband son for 3 years now he`s 5.This will be my first pregnancy :)
My dad is a old school kind of father. My mom and his mom has been asking for the past two years for a baby. I kept pushing it off due to being scared. I want to plan something nice to tell them I'm pregnant . Any ideas ??
