Or even better, teach your children what isn't safe to eat so that when the fancy strikes them they don't eat poison. Regardless of whether or not it is in your yard, this can only benefit them.
They might. My sister and I would crush up plants when we were little to make “potions.” We stopped when we made a potion with Serrano peppers at my aunt’s house in Mexico, at least it wasn’t some deadly plants.
Yes. We live in the woods in northern Illinois, and we have taught them to identify wild raspberries and blackberries. They don't eat without running it by us first. That said, I would try to avoid intentionally planting toxic plants in the yard due to both kids and pets.
