Grandson Birthday Wishes & Quotes: Birthday Messages for Grandsons

By Tom (for his 12-year-old grandson)

90+ Grandson Birthday Wishes to Show How Much You Love Him

Being 12 is right in so many ways,
It’s over four thousand three hundred days,
The inches in a foot and months in a year,
The days of Christmas full of good cheer. 

It’s a carton of eggs and donuts in a box,
The Zodiac signs and hours on a clock,
Roses, birthstones and drummers in a song,
The end of the tweens, where you belong.

But best of all,
As you grow tall,
We'll tell stories of a life lived well,
Of the wonderful you turning 12.

Happy birthday!

Hints & Tips

How do you write grandson birthday wishes?

Creating the right grandson birthday wishes for an eCard, Instagram or Facebook, one that he will cherish long after his special day, can be a little daunting, especially if your grandson is a teenager or young man. 

What should you write in your grandson's birthday card?

The best way to say "happy birthday" to your grandson is to let him know how much you love him and admire what he has done with his life, so let your feelings be your guide.

Of course, when it comes to grandson birthday wishes, you can take the easy route and underwhelm him, or the better route and create a lasting memory. 

What's the easy route? What's the better route?  

The easy route is the safe way to go. It's the route that leads to writing what I call "typical" grandson birthday wishes — the type he'll read for a second and discard without a moment's hesitation.

Sure, your grandson won't be offended by this kind of birthday wish — that's what makes it safe. But he also won't remember it after a few moments. This, I presume, is not what you want to happen. 

The better route takes into consideration your grandson's age and your type of grandparenting. Based on these factors, I will suggest the best kind of grandson birthday wishes you should create for your grandson.

This way, your grandson birthday wishes will be a keepsake that he'll cherish forever, whether you put it into a card, on an eCard, on his Facebook page, in a text, wherever) That's what you're aiming for, right? 

First of all, let's look at your grandson's age, before you write birthday greetings for him:

  1. If your grandson is 13 and under, he will likely care more about his gift than his birthday wish. So, for the young ones, stick to pleasant, typical, well-written grandson birthday wishes. I know I mentioned only a few moments ago that this type of birthday greeting is not as good as the alternative but he's going to discard it anyway and make a mad dash for the cash or gift card he wants you to give him. 
  2. If your grandson is 14 and up, you can assume that he has the maturity to appreciate great grandson birthday wishes when he sees them. If so, this is where your grandparenting style comes into play. 

According to an article I just read on ("Five types of grandparents and how they shape our lives"), there are five basic styles of grandparenting. See if you can identify with one of them: 

  1. The formal grandparent: You follow the standard rules of grandparenting, providing occasional services (not just babysitting) and maintaining an interest in your grandson, but you're not too involved in his life. 
  2. The fun seeker: You're the fun grandparent — you like to provide entertainment for your grandson. 
  3. The surrogate parent: You are or were the primary caregiver for your grandson.
  4. The patriarch (or matriarch): You not only dispense advice and money — you also "control" the parents of your grandson. 
  5. The distant figure: You have infrequent contact with your grandson, appearing only on holidays and special occasions. 

And now for the grandson birthday wishes you should choose based on your style of grandparenting: 

  • Birthday wishes from the formal grandparent: Write so-called "happy" birthday wishes. Any other style may make you and your grandson feel uncomfortable. 
  • Birthday messages from the fun seeker: Write funny, cute or clever grandson birthday wishes. Each type has a certain "fun" quality
  • Birthday greetings from the surrogate parent: Opt for sentimental grandson birthday wishes (you've earned the right to pick a heartwarming birthday greeting). 
  • Birthday wishes from the wise patriarch (or matriarch): Take the inspirational birthday wish route. It's the best way to dispense advice. 
  • Birthday messages from the distant figure: Write "happy" birthday wishes (anything else would likely be awkward for you and your grandson). 

You'll find all these styles (and more) on this page, so it should take you only a few minutes to write the right one from all the examples of grandson birthday wishes here.

If your relationship is a mix of the types I mentioned above, what’s the best route? Probably a mix of cute and happy...with a touch of the sentimental (and the right amount of inspiration).

In any case, simply start with an option above that best captures your grandparenting style and go from there, adding your personal touch.
