The Teal Pumpkin project is a worldwide movement that offers an alternative to candy on Halloween, for kids with food allergies as well as other children for whom candy is not an option. The idea has taken off in recent years.
Putting a teal pumpkin on your doorstep means you have non-food treats available, such as glow sticks or small toys. This simple act promotes inclusion for trick-or-treaters with food allergies or other conditions.
