Accepting a child with an epipen is a challenge, but I had a little girl in my care who had peanuts and tree nuts allergies and carried an epipen too. The family provided one for me to keep in my medical emergency pouch that goes everywhere with us so it was always with me. I advised the other families the same way you did and taught the other children to watch out for nutshells at the park because people feed nuts to the squirrels.

Reading labels was the hard part. I didn't realize you can't even serve some rice cakes and things like that because they may have trace of nuts. But if you cook from scratch like I do it's a minor problem.
