Baby Chain
I saw the strangest thing today, a sort of mass harness for children similar to what you’d expect to find for huskies on the front of a sled. The middle was a long piece of quite stiff material from which about 8 harnesses (4 either side) came off. At the front was a handle that an adult could hold onto. The kids (fairly young) were then chained to this bright yellow contraption and taken for a walk. I suppose walking in front guiding the children is fine. It’s only when you’re sitting in a sled behind with the children pulling you that it becomes cruel 
No photo as I’m not overly keen on taking pictures of kids for fear of being branded some kind of peado.
I’ve seen those too. Even just the little backpacks for one child are common here. It’d be kinda fun to be pulled on a sled by children.
