21 month old ds spends a lot of time scrabbling around in the corner of the playground, poking the earth about with a stick, picking up stones and weeds. We don't have a garden so we are there every day for an hour or two. A few days ago we found a dead mole in that corner, lying prostrate on the earth. I feel the council workers must have poisoned it, very unusual for a mole to die out on the ground of natural causes, and now i'm worried that Ds might have ingested some poison, maybe not enough to hurt him short term but not very nice long term. Am i worrying unneccesarily or would you be worried?
