Not a mistake, just something that happened. If it wasn't that, it would be something else eventually.
For me, specific episodes of the Waltons and Little House on the Prairie triggered bedtime fears and rituals that lasted for years. I'm quite sure my parents didn't expect anything from letting me watch the shows. Nor did I say a word to them, because I was the sort of kid who was embarrassed to share those sorts of thoughts. So be glad yours is telling you!
Prior posters have advice, but please, don't beat yourself over this happening!
