Don’t have demonic children
Out of all of the lessons you can get from watching horror movies, this has to be one of the top ones. If you’re going to have kids, do your best to make sure that they’re not demonic. We know that the love for your child is unconditional, but if it has slightly demonic tendencies, you’re going to have a bad time.
What do you do when your child is a literal demon spawn? That’s for you to decide, but we’ve seen far too many horror movies to make light of the situation. It’s like one of the old “if your child was Hitler, what would you do?” scenarios. If it ain’t your child, you can make the right decision.
