Announcement idea?

Alicia1111

I am so excited to announce I'm expecting baby #2. We have been throwing around ideas how to tell out extended family and friends (Our parents already know) I have a 15 month old who loves to play with books. i was thinking of having her hold my "what to expect when your expecting" book like she's reading it. And post/send out the picture.  Do you think people will understand? Or am I totally over thinking and should just tell everyone on my own?
