Announcing?

I’m 7 weeks today with twins ! We are NOT announcing we’re having twins just that we’re expecting ! We are not telling anyone we’re having twins until they are born! If they are both one gender we’ll be announcing the gender but if not and it’s boy/girl we will be keeping the genders a secret as well! Since we can’t post an ultrasound we are thinking of using a BIG BROTHER shirt on our 9 month old! We don’t know exactly when we will. Maybe around the 13-15 week mark

How are YOU announcing and when ?
