Our second baby!

Shelby • Expecting baby number 2!
So before anyone judges. I am happily married.  But I don't know how to go about telling my parents I'm pregnant! My first child I got pregnant at 16 and had him when I was 17 now a year later I'm 18 & due in February. I take care of my child and we have a great job everything we need for a child. But to my parents. I'm a failure to life. I'm so scared and nervous about how to tell them! Can ANYONE please give me some advise about how to bring this up?!
