What to Write in a Lunchbox Note: 60+ Examples by Age
A practical writing guide · Examples for every age, from first preschool lunches to the last year of high school
Every parent who has stared at a blank sticky note at 7:40 a.m. knows the problem: you want to write something, and nothing comes to mind except "Have a great day!" — again. The good news: a great lunchbox note doesn't need to be original poetry. It needs to be short, specific, and clearly from you. Here are more than sixty copy-ready examples sorted by age, because what delights a four-year-old will make a fourteen-year-old sink through the cafeteria floor.
The 20-second formula
If you remember nothing else, remember this: one true thing + one warm thing. One true thing is a small observation — something they did, said, built, tried, or are about to face. One warm thing is how you feel about it. "Your tower was taller than you yesterday. I'm still thinking about it" beats any generic compliment, because it proves you actually notice their life. Keep notes to one to three lines. A lunchbox note is a postcard, not a letter: it should be readable in the time it takes to open a sandwich.
Rotate your material so the notes stay surprising. Across a school week, try one joke, one encouragement, one question they'd enjoy debating, one fun fact, and one simple "thinking of you." Our Note Maker is built around exactly that rotation — five themes plus kindness challenges, so no two weeks feel the same.
Ages 2–5: toddlers and preschoolers
Little kids can't read yet — and that's fine. For this age, the note is really a ritual object: they recognize the paper, the drawing, and the fact that it came from you. Teachers often read notes aloud, so keep the words simple enough to be read to them. Big wins at this age are drawings (a heart, a star, their favorite animal), stickers, and notes that mention something concrete and comforting.
"You are my sunshine. See you after nap time!"
"I packed your favorite cheese stars. Crunch, crunch!"
"Draw a circle on the back of this note and show your teacher."
"A big hug is hiding in this note. Open it whenever you need one."
"You are brave, you are kind, you are YOU."
"Guess what? I love you more than all the bubbles in the bath."
More toddler-friendly starters: "Today is a (their favorite colour) day — look for three things that colour." "Your job today: one big roar like a lion." "Mommy/Daddy is thinking of you right now." Keep sentences under six words where you can, and never write anything you'd mind a teacher reading out loud.
Ages 6–8: early readers
New readers are proud readers. Short notes they can decode themselves feel like treasure, and jokes they can retell are social gold in the cafeteria. This is the golden age of the knock-knock joke, the riddle, and the "would you rather" question. Mix in encouragement that names a real effort — learning to read itself, tying laces, raising a hand in class.
"Why did the cookie go to the doctor? Because it was feeling crumby!"
"You read three whole pages by yourself last night. Superstar."
"Would you rather have wings or a tail? Tell me at dinner."
"Fun fact: sea otters hold hands so they don't float away. I'd hold your hand too."
"Today's mission: make one person smile. I bet you can."
"Mistakes are just clues. Collect as many as you can today."
More lines for this age: "I'm proud of how hard you practice." "Count how many red things you see today." Questions work especially well because they give the note a reply — your child comes home with an answer, and the note becomes a conversation instead of a broadcast.
Ages 9–12: tweens
Tweens still love lunchbox notes — they just don't want anyone to know. Keep them shorter, cooler, and easier to hide. Humour lands better than sentiment at this age, and specific respect lands better than either: noticing their skill, their taste, or their effort without gushing. Fun facts and genuinely tricky "would you rather" questions are perfect because they can be shared with friends without embarrassment.
"Fun fact: honey never spoils. Archaeologists have tasted 3,000-year-old honey."
"That save in practice yesterday? Goalkeepers everywhere are jealous."
"Would you rather always whisper or always shout? Choose wisely."
"New joke: What do you call a fish with no eyes? A fsh."
"You've handled every hard thing so far. Today's thing doesn't stand a chance."
"Playlist update: your new favorite song is actually good. Don't tell anyone I said that."
Avoid babyish fonts and hearts-overload for this group — our Minimal and Doodle designs in the Note Maker were made with tweens in mind. A note that says "Quiz at 3pm. You've done the work. Just show it what you know" respects their competence far more than a page of exclamation marks.
Ages 13+: teens
For teenagers, the lunchbox note becomes the packed-lunch note, the locker note, or the note in the gym bag — and the tone matters more than ever. Short is everything. Dry humour, genuine respect, and zero public embarrassment. Never write anything that would mortify them if a friend glimpsed it. The notes teens secretly keep for years are the ones that treat them like capable people.
"Rough week. Good human. Both can be true."
"Coffee money in the side pocket. You've earned it."
"No pep talk today. Just: I've seen your work ethic. Trust it."
"Fun fact: your brain is about 73% water. Hydrate before the exam."
"Dinner vote tonight is yours. Choose powerfully."
"Proud of who you're becoming. That's all."
Practical notes count double for teens: a heads-up that you moved their shift money, a reminder that pickup is at 5, an apology for a rushed morning. A parent who uses notes for real communication — not just cheerleading — gets read every time.
Notes for specific days
First day of school
Name the nerves instead of denying them: "New school, first day. Everyone there is hoping to make a friend — be the easy one to talk to." Or simply: "You don't have to be the best today. Just be kind and curious. Home by 3:30, snacks waiting."
Test and performance days
Keep it light and pressure-free: "You've done the preparing part. This part is just showing up." Avoid "I know you'll get an A" — it quietly adds weight. (Our guide on what child psychologists suggest explains why.)
After a hard day yesterday
Acknowledge, don't analyse: "Yesterday was rough. Today is a new page. Also, I packed the good cookies."
Birthdays and celebrations
Go bigger: a note in the lunchbox, one in the backpack, one in a shoe. Quantity is the message.
When you have zero ideas
Steal from the bank. That's literally what LunchNotes is for: open the Note Library, search a word like "brave" or "shark," and print the one that fits today — or generate a whole sheet in the Note Maker and never think about it again until next Sunday. The best lunchbox note is the one that actually makes it into the lunchbox, and a printed one beats a perfect handwritten one that never happened.
