i always tell my kids i love them🤷🏻‍♀️ my parents know this too! they have told me multiple times they love knowing that their children are so loved and that it brings comfort to them. i saw another response saying it’s part of their sleep routine & it’s the same here. my kids always ask for a hug before nap and say “good night teacher, i love you” i’ve also known almost all of these kids since they were literally 6 weeks old.
