To date, I've shared very little. My husband, however, has shared with his mother that I've hired a doula, plan to have a non-hospital birth, and a few other tidbits. He hasn't just shared out of the blue; she asks things like, "what hospital is Like.Australia having the baby," which is followed up by "but why? who is going to be there then? what is an Abdula?" Ugh. I've asked him to share as little as possible and to play dumb, if necessary, in the future.
