A good friend of mine is pregnant with twin girls. She is a nice enough person, but can be somewhat demanding and is also prone to oversharing things on social media occasionally. A few examples are that when she became pregnant, she was straight on to facebook to post photos of the positive test. She has also posted photos of herself with her belly wrapped in two pink ribbons, along with her DH kissing her bump. She has commented that she is hoping that people will get two gifts for the babies instead of just one. What do you think the etiquette is here? Would you only ever buy one present for someone even if they are having twins?
