Announcement Ideas????

Jazmere • 24. Army Wife. Mother. Hebrew 11:1 "Now faith is being sure of what we hope for and certain of what we do not see"
How are you ladies announcing??
We plan on announcing Valentine's Day( we will be around 12 weeks and it's a couple of days before my husband's birthday!
How should we announce?
* We are military so my family won't be around until the gender reveal and we haven't told them or his NCO's* 
This will be our rainbow baby so I'm not sure if we should do valentines or rainbow themed *
