Age is one of the milestones in the life of any young person that happens at the age of 18. It is a sign of the transition between childhood and adulthood, the stage that is exciting, promising, owning responsibility, and being unaware of what exactly lies beyond the horizon. When one is 18, the world starts to open up in a way it has never opened up before. Decisions become deeper, fantasies begin to seem nearer, and the path to independence is in fact underway.

To your grandson, it is not merely another candle on the cake, this birthday. It is the entrance to the self discovery, self development, and the development of his personal self. It is the place when he starts to enter his strong side, overcome new problems, and understand how to decide his future. It is at this point that the boy that he used to be changed into the young man that he is supposed to be.

And you, as a grand-parent, can give him nothing lovelier or more significant or empowering than your love, your wisdom and your hearty blessings. An ideal happy 18th birthday grandson message will not be a greeting but a gift of advice, of the way he is so much loved, and of the inspiration which he can keep all his life. It takes a grandparent to combine love, experience, encouragement, and pride so naturally, in such a genuine manner in giving words that remain with him even after the candles are extinguished.

Why turning 18 is so special

A happy 18th birthday grandson is more than just a celebration, it is a mark of a turning point. It is the time when your grandson has become a man, with his confidence, curiosity, and dreams, which he acquired in the course of years. 

At 18, your grandson:

Gains more independence: He starts taking choices that define his course- his schooling, career, friendships, and even to himself.

Major decisions in life: It is at this age that he begins to make decisions on what he believes in, wants, and who he wants to be.

Builds long-term goals: His future is not just not very far, but something he is pursuing.

Grows up building his character and dreams: He is also finding his passions, passions and values that will make his adulthood.

Plays the roles and at the same time explores the world: He is learning the way to live in freedom, responsibility, adventure, and ambition simultaneously.

How to write the perfect 18th birthday message for your grandson

Creating the ideal message to a happy 18th birthday grandson is an opportunity to honor who he is, who he is becoming, and the superb future ahead of him. You can write a card or a text or a loving letter and you will say more to him than he will ever utter in a voice. This is the way to make sure your message is memorable:

A memory

Perhaps it is the day when he first walked, or the day he made the entire family laugh or the day you understood that he has become a kind and thoughtful young man. Reliving a memory will help him remember how long it has been since he passed through the same thing that you are going through and also makes your emotional relationship stronger.

Words of wisdom

Happy 18th birthday grandson and he is entering adulthood, with its options, freedom, responsibilities, and new experiences.

Give him plain, sincere counsel, which he can bear:

-Be brave enough to try.

-Be wise enough to think.

-Will you mind making a difference?

Even a few words of advice from a grandparent can resonate in his head even years later.

Encouragement

Adult life may be exciting and daunting. Take this time to remind him of his strengths, his will and the potential that you have seen in him since the start. Tell him he has all he needs to achieve-and that he can count upon you.

Love & pride

Your love should be well articulated in no message. Warm him that you are proud of the person he is becoming, responsible, thoughtful, funny, strong, or compassionate. The words of your love still hold a lot of weight even in a young adult acting independent. Indeed, they can have a new meaning than ever.
