When you put it that way, it really seems to be a unique thing in the world. The note, well, you don’t just wish him a “happy birthday.” Instead, you get sidetracked into remembering his growth pace, his laugh, and his hugs that would exactly characterize love putting into words. So, yes, indeed, this post totally revolves around expressing those sentiments in a proper way. Something quite brief. Little sweet. Completely real.
Why Simple Words Matter Most
The idea is not to produce a long novel in your writing. In one or two lines, you can already explain everything. Most importantly, these little lines should come from your heart. Maybe as a text you are sending. Maybe writing it in a card. Maybe, quite possibly, saying it aloud via video call. The point is that it does not really matter. What really matters is that you sound like yourself.
Suppose a woman is smiling at the moment while she is writing a birthday card and has a cup of tea next to her that she is probably going to drink. Table at which a woman is writing a birthday card for her grandson is shown in the picture.

So if you are feeling indecisive? First, start with what you are familiar with. Then write down what you feel. That will do. If you’re looking for more birthday wishes for grandson, you can find additional ideas and examples to help you get started.

Writing Birthday Notes When You’re Not a “Writer”
Some people don’t enjoy writing. That is OK. But that doesn’t prevent you from saying something heartfelt. Picture a memory. A habit he does that you love. The way he made you laugh. Write that down. Even half a sentence can have an impact.
- Describe what number of years old he will be and give one reason of your pride.
- Introduce by saying “Remember when…” and recount a short memory.
- Be honest. Even the phrase “Happy Birthday. Love you always.” is suitable.

How to Make the Message Better
- Small things are the best. It is not necessary to be the main event of the message.
- Write one of the funny names you have for him
- Talk of his closest snack or favorite pastime
- Insert a joke from the past that you still find funny
- List one thing you love about his manner of talking to people
Handwritten vs Digital Notes: Which Way Feels Better?
Do you like pen and paper? If yes, then that is how you should go. There is a certain charm in a handwritten note. Particularly if you have something like a birthday card message for grandson that adds a personal touch he’ll remember.
- Stickers
- A small photo from when he was a child
- A $5 bill with “for birthday snacks” written on it
- Your signature in that cursive style that he always makes fun of
But if you are more into texting, then that works just as well. A casual message that sounds like your voice? Still a heartfelt one.

FAQs
1. What aspects of my life should I write about to my teenage grandson on his birthday?
I would recommend writing nothing complicated—just be true to yourself. Highlight a characteristic of him you liked or a moment you shared that was enjoyable.
2. Can I just send a short message by text?
Yes, why not? Two lines of thoughtful text can have the same effect as a card. And even then it is important that it remains personal.
3. Should I include a gift with the birthday note?
If only you wanted to. The note sometimes is more valuable than the money. Whereas the truth be told—teens like a little cash too.
4. I am not close with my grandson—what do I say?
Maybe keep it safe and sound and say something nice. Even the simplest “Have a nice day” works well. Who knows it might become a key to the door?
5. Is humorous writing tone acceptable in birthday notes?
Humor is one of the things that can make your style stand out. If that’s your style then definitely do it. The power of a joke is not far from the heart, especially from Grandma or Grandpa.
