My MIL posts extensively on FB so it's second nature for her to share news about family through her account. When our son was born, she announced the birth via FB hours after I gave birth and while I was still in hospital. We'd shared photos via WhatsApp and she included these even though part of my boob was showing due to skin-to-skin (they were discreet and I was comfortable with family seeing them but not with them being shared with everyone I know!) She tagged both me and my husband so our friends, colleagues and my aunt/cousins found out via this route before we could tell them in person. With hindsight I think I'm entitled to feel pretty upset about this but at the time we were preoccupied adjusting to life as new parents and didn't want a drama, especially as we hadn't been proactive in managing her expectations around social media during the pregnancy. We therefore didn't challenge it though she did sort of apologise to my husband and acknowledge she'd thought that maybe she shouldn't do it but was too excited! My husband and I both have FB accounts but haven't actively used them in years and are quite private people so wouldn't have made our own announcement. During the first few visits she posted a LOT of photos of our son which made us quite uncomfortable. We therefore explained we wanted to keep photos of him off social media and asked her not to post any new photos. A couple of times we've had to ask her to take new images down but she's now much more respectful. However, there are still posts up with our son's first and middle names, DOB, mother's maiden name and name of village where we live. I'm concerned about this from a security perspective and am planning on asking her to remove these even though it's several months after the event. I don't think she gets why we're concerned and thinks we're being paranoid. AIBU? For context she has 500+ FB friends and lax privacy settings. Posts she's tagged us in are shared with a further 400+. If anyone knows of any relevant resources about internet safety we could share I'd be very grateful - most info I've found is aimed at stopping children oversharing, not their Nan!
