banning photos of my DC on SM

[WispaGoldsshouldcomeinmultipac]

Afternoon all!

Popular topic, just looking for advice on how to deal with the fall out of deciding that there are to be no photos of my DC on SM.

MIL went mental - apparently DP and I have stopped her showing off her grandchild - mutual decision from us both and other family members have said they'll post regardless.
AIBU? Is it a thing to do? DP and I are quite private and we don't have the time to be policing social media to report pictures.

How did other people deal with this? TIA

YANBU. My DH and I share the odd picture of our baby on SM because we don't mind our friends and family seeing it but I don't really likely when others share photos.
I have had friends put up photos that were sent on a private whatsapp too.
Not their child, not theirs to share. End of.
