I’ve found similar things with kids but what I often do myself is take on the role of the parent in the situation, besides being one, and teach the kids about the squirrels and educate them on how to treat them and stuff. It goes a long way and actually quite helps the kids, and I often get remarks from the parents like thanks and that was great. Some don’t appreciate it but I would say 75% of the kids love it and most of the parents do as well.
It’s not easy but I try as much as possible to “be the change you want to see” and it goes a long way to do so!
That's a great way to handle it!
