I don't have any small kids, and neither do my close neighbors. As soon as Myah had her shots, I took her to the park and playground regularly. Very regularly! I taught her "go say hi!" in a happy voice and she started to get a kid following. I would get texts from families who would ask me if I was bringing Myah to the park, so they could plan to come at the same time!
Of course, there were shy kids and cautious parents, which is normal. But they would watch the confident kids having fun with her and soon relaxed.
I always kept her on a leash (following leash laws).
Here she is when she was about 5 months, I think.
