It looks fine when there are no babies in it, but when you actually see it with passengers, it's quite obvious one of the children is getting a raw deal. While the baby up top has access to street views, interaction with people, enough room to kick if so inclined, the bottom baby is simply staring at the mesh padding of the seat in front of it. I even saw one mother toss her purse in with the bottom baby. That's not storage, ma'am. You have a baby in there. Years from now, studies will show that the child sitting in the bottom seat is someone who prefers to stare at walls.
But things could be worse. The other day in the park I noticed a child too scared to approach a group of dogs that were playing together. The boy took a few steps in the direction of the dogs, and then ran back to his mother. This continued until finally, the mother picked him up, put him into her granny cart, and wheeled him into the circle of dogs. This is a granny cart if unfamiliar:
It was like a shark tank cage for a puppy play date. The little kid stuck his fingers out of the cart to pet some of the dogs, and when he started to get scared again, the mother would wheel him out backwards.
As I watched this, I felt like I was witnessing the reason why therapy exists.
Sadly, this was not the first time I've seen a granny cart used as a stroller. One time in Queens Brina pointed out a woman pushing her two kids down the street in a granny cart. The kids were standing upright and secured in the cart with what appeared to be some sort of luggage strap. Obviously there were some safety issues there, but at least both kids had the same view.
