My Sneaky Treats

Ever since my kids started bringing snacks and candies from school, I've felt like I'm on a treasure hunt. One day, while they were playing outside, I discovered an unopened bag of cookies under the couch, it was too tempting! So there I was, munching away when they came in. I quickly stuffed it back and pretended nothing happened. Now every time I find snacks, my guilty conscience kicks in. Is this normal for a parent to enjoy sneaking secret treats? Should I just start buying them their own stash so we both win?
