Third time mom

Diana • 37 mom of 2! I teach music, love reading, cooking, baking, and being with my family.
For some reason I just don't feel like sharing with the world about this pregnancy. I have two kids but this is my 4th pregnancy. I'm wondering if it's my age or the number of pregnancies I've had but I just want to enjoy this one much more privately and low key. Outside of my immediate family, do you think I owe it to extended family or friends to my FB/IG updates & pics?
