My entire family rags me because I don’t post pics of my kids on the Internet and I don’t allow my family to post pics either. This is exactly why I have that policy. There is just no way to know what someone else might consider child abuse.
I have a libinlaw that is an example of what you’re stating - that anything could be reported as child abuse.
My kids were in a homeschool publication this month.
My MIL was looking through it and was appalled and nearly “outraged” that the girls were all dressed so conservatively.
I teased her by going along.
“How dare they dress like that! They look so wholesome! There should be a law against that!”
