If you see someone who's kid isn't on their carseat properly (or not on a carseat at all!) or with the wrong kind of crib (just an example- with bumpers and full of blankets) do you let it go or say something?
I made ONE comment. ONCE. My SIL proudly was posting pics of her neice (on her side of the family) and in one of the pics a little girl about the age of EIGHT was standing on an OPEN OVEN DOOR! 18 people from her family commented on the pic ohhhing and aweing over how cute "aunties little helper was" but nobody said anything about how dangerous it was. I simply said, Susan, that little girl is so adorable but what she is doing is sooooo dangerous! The entire oven could tip with her. Is it bolted to the wall/floor? Not only did I get told I was a ****ing bit*h and to mind my own business.......I was also told that Hell NO, it was not bolted because that was stupid and "besides, I (meaning SIL) was watching her the entire time". Now remember, the pic was taken from ACROSS the room of SIL's huge kitchen, by SIL! By the way, before that comment, SIL and I had NEVER once had a bad word between us in the whole 12 years I had known her.
Nope. I don't even notice that stuff. If I am completely honest, unless you are one of my best friends, I do not even look at the photos of the kids. Unless they are like, freakishly ugly or something, and then it is just a "Holy shit! Honey, look at this kid. He looks like Smegle!"
