Announcement thoughts

Monica • I`m a 25 year old military wife and mother to our 5 year old son, Rylan and our sweet Maci born 7-17-15.
As we are all waiting on our BFP's has anyone though of any special ways to announce it to their SO or families? For my husband I want to ask him to take a picture with our son (3) and instead of a picture I want to be recording, then say "okay, on the count of tree...one,two,three, say "Rylan's gonna be a big brother!"" And catch his reaction on tape!! :) As for our families, I'm not sure since they are in Texas and us in California. If I get a BFP in Jan I was thinking on Valentines day I could send pink and blue flowers to my mom and MIL that says "on this Valentines day, we'd like to announce that there will be a 4th Valentin (our last name) to add to our family." Or something like that. Have any of y'all thought about cool announcement ways? For our first we just sort if called and told everyone.
