Remember, if your child has allergies make sure they wear their wristbands with allergy information. Provide sweet/candy bags to be given to the child in advance, or, you can do what this dad did. If you are staying home and giving candy out, be mindful of what you are giving. When parents come to the door with their children, ask if any have allergies to the candy you have before giving it out. If children come to the door without parents, look for medical wristbands.
Alternatively, instead of candy you can also find toy party items like bouncy balls and fun bendy straws at the local dollar store that can be passed out instead of candy.
Have a happy (and safe) Halloween!
