Pregnancy Announcements

Br
Hi ladies!
So I am trying to come up with ways to announce my pregnancy. I am barely 4 weeks, so will be announcing it sometimearound New Years. 
How did you ladies announce your pregnancies? Could any of you post some pics for me? 
This is my 2nd baby. And my son is 6, and would love to incorporate the 'big brother' thing into it if I can. He is sooo excited!
Ideas, ideas, ideas, please! 👶🏻💗💙
