First, there’s your child’s maturity level. All children are different, and while some are ready, others are not, and vice versa. Consider how well your child copes with other things, and use that to gauge your response.
Then there’s your neighbourhood. If it’s quiet, and safe, without any busy roads, then it may be okay, unlike neighbourhoods that are busy and have lots of traffic.
Another point to remember, even if you do decide that your child is ready to trick or treat alone, is that you should never let your child go alone. A favourite baby sitter can replace you if your child doesn’t want you to come along, or he or she can go trick or treating with friends. Make sure you know their route and that you set a time for your child to be back home.
