Personally…..my babies were never on the floor anywhere in public. Putting my feelings to the side, the pictures shows that the baby is on a blanket with people standing around the baby to protect it, so it’s probably not anything irresponsible. Why the baby is there? Who knows - maybe a babysitter canceled and they had no choice and didn’t want to waste the ticket.
It’s tough for me to judge people about something like this without knowing the full story. I know people judged me because my oldest DD, when she was little, was in a stroller all the time and on a leash, because she’d run away and she was super fast. So for her protection, I did what I had to do, despite the crappy looks I’d get from people. It was either put her on a leash or have her get run over by a car - definitely a no brainer for me. But others looked at me like I was a horrible mom.
