I wanted to go on walks during nursery time, but was worried about losing a child. I knew they had "field trip ropes" for young children to hold onto and wanted something like that. However, when I priced them, they were too expensive for a nursery budget. So I bought some inexpensive rope, used some canning rings, an old sock, and created "Sammy the Snake." When we go on walks, the kids have to hold onto Sammy so he doesn't get away. It works well.
