1. We regularly share photos through private photo albums. This allows her the same exposure to photos of the grandchildren as social media would.
2. We made it clear she's free to share photos with people via direct text messages. It adds a bit of friction and keeps the photos relatively private.
3. Explained that it's the right of our children to control their presence online (with some parental assistance). They aren't old enough to do that so until then, please don't share.
4. Emphasize many times that it's about protecting and empowering our kids. It's not about preventing her from showing off her grandchildren.
