The reason I asked is that once a month or so, someone on my local posts about someone they saw (usually at daycare, but sometimes just out in public or whatever) that was doin' it wrong when it came to car seat safety and it's always posted with, "Oh noes! What should I do/have done?!" Most people are either, "Call the cops!" or "Tell the director!" I just think, "MYOB?"
The posts come off as quite judgy and like these people are on the lookout for this isht.
I'm in the Hmo camp, I'm too busy handling DefConn that I really don't notice what other people do with their kids.
