My quandary is this: husbands family LOVES social media and I am not a fan. With the twins, they were all over the place, posting photos and videos, numerous status updates, etc., which was great bc the parents didn't mind. However, I'm a very private person and I DO NOT want this once-in-a-lifetime moment to develop into a million status updates/tags or have my newborns photos shared with who knows who on social. However, I also don't want to squash their excitement. 

How do my husband and I nicely but firmly ask them to respect our wishes for sharing on social without me coming off as the super controlling DIL? I really don't want to deal with comparisons to my BIL/SIL on delivery day since what I prefer is so drastically different than what the family experienced with the twins birth. I also am not wanting many people at the birth and don't want a lot of visitors afterwards, which is going to upset ppl who want to be there during/immediately after delivery. I'm struggling between wanting to do what I know is best for me and my personality (very private) and what his family is expecting. What to do???
