How to announce baby?

Jay

Been thinking about baby announcements...I'm only 7 weeks but want to plan ahead. I'm thinking of a social media announcement around August/sept, but was wondering....are you supposed to do a them based on time of year you announce, or based on due date? So if I'm due in Feb, do I announce using a valentines theme or find a holiday around August/sept to announce? I can't think of any for the latter (Labor Day maybe?). Thoughts???
