Husband shows "The Shining"trailer to our 5yo son

My husband thought it’d be funny to show our 5-year-old son a scary movie trailer, and now bedtime is a total nightmare. I’m honestly so frustrated because I just want our kid to feel safe at home, not scared of the dark! I know he didn’t mean any harm, but seriously, why do dads think this stuff is funny? Now we’re dealing with extra nightlights, monster checks, and lots of hugs. Any tips for undoing the damage? Or am I just doomed to sleep with a little shadow for the next month? Would love to hear if anyone else has been through this and how you handled it! #ParentingFails #MomLife #RealTalk #Parenting
