I'm not a mom...but what you have already sounds good to me!
But my mom never used to write me notes but then like a couple years ago when I was like 11 my parents went on a cruise so my aunt and uncle watched us and it was so funny because my uncle sent us like a "weather" themed lunch. It was so corny but I loved it! He wrote a note telling what the weather is going to be like, what we're doing tonight, little doodles, and other stuff. He cut the sandwich in a sun pattern. It was cute LOL.
I'm easily made happy

But it was fun. Sorry for the story, Haha, I'm sure it didn't help much but yeah.
