Break the news?!

Heather Marie • HG survivor! My heart & soul William was born 4/26/16 6lbs 9oz. 19.5" long. Baby #2 on the way! 👶🏼💙
I feel really nervous to break the news to my family & in laws. Also my older sister isn't married yet or have any children. I'm worried she will hate me. My mother in law is very judge mental and thinks she knows everything about everything. I know she will be telling me what to do or that I'm doing everything wrong the entire time! How do you think I should deal with this? So frustrating! I'm nervous they will be all rude and think I'm too young just because I still look like I'm 15 & I'm really short! My husband and I have been together for over 14 years and married for 3. He is 30 & I am 27. We're moving into our first home this October. Help! How do u deal with judge mental family members?
