Halloween candy is a multi-billion-dollar business. But for parents, too many sweet treats can be a big headache. From Candy Corn to chocolate---the Halloween sugar rush is expected to add up to a sweet $2.1 million in sales. And, with so much candy going around in the neighborhood, at school, and at parties—Parents may want to map out a strategy for that Halloween haul. Parents of children with allergies need to take particular care. CARE.COM recommends inspecting labels on each piece of candy a child eats-Even if it’s a brand they’ve had before, as ingredients can change. Teach those children not to eat anything without a label, and send them to parties with a bag of candy that’s safe for their allergies, so they don’t miss out on the fun.
