Announcing to the in laws now it's time for my parents

Jess
Well last night we announced to my MIL and her boyfriend and my brother in law and his wife that we are expecting! And now this weekend it's time to tell my FIL and his wife! So nerve wrecking but exciting all at the same time! This is how we announced to my MIL 
And this weekend this is how we are telling my FIL...
How and when do you plan on telling your family?
