Bitch sister in law

I just need to vent for a second...

Let me preface by saying my husband and I typically don't post pictures of our son on social media. The only exception was the Gerber baby contest. But regardless we ask that other people don't post his pictures. They are not his parents and we don't know who is seeing their social media.

So my sister in laws son was recently baptised and my husband and son went up to NY for it. Well about a week after, she had a post on Instagram of our son with his cousins in the picture. I don't care if anyone else is in the picture we don't want our son on social media. Especially posted by someone other than his parents. So my husband ask her to remove it and she proceeds to argue with him that I have already posted pictures of him on social media. She has not spoken to him since that day. Wtf there should be no argument... She knows how we stand on the issue it's not her kid. And this is not the first time she has done this. Agree or disagree when someone asks you to take a picture of their child off social media, family or not, you do it without argument.
