What should I write to my grandchildren?

A sheet of paper that you think will represent your characteristics will be great. Think of something like paper with flower patterns, or maybe with a monogram letterhead. An ivory sheet of paper is a good choice. Pick a proper pen that slides easily on your sheet; a pen colour like fluorescent pink ink may be perfect.
Before you start, if you have an application to type your thoughts, prepare what you want to write down in the application before grabbing the pen, then copy your letter on your sheet.
What do you want to say? What is the sensation you want to convey? Do you want to welcome them into your life? Praise them for an accomplishment they have done? Show empathy to them in rough times?
Although there is no need to know what you want to say beforehand, you need to know why you intend to write and the gist of things you want to express. Date your letter at the beginning. Your letter will be kept and cherished for years, so it’s essential to specify the date in the letter for your grandchildren to reference later when they come across it on a bookshelf or find it hiding between pages of a book of their earlier ages.
Be yourself. You don’t have to write like ” Dear Bob, considering…” you don’t need to write formally. Stick with the way you usually talk to your grandchildren. And also you don’t have to write your letter in some fine handwriting, do it neatly in your way. If you think your babe will read it themselves, go for printing rather than cursive.
Start your letter with a loving statement asking about your babe’s well-being. “I wish you a great day.” or something like, “if they have been through hard days, raise your concern about the situation, something like “How are you getting along with _____?” Or, for a newborn grandchild, a warm and straightforward opening like ‘Welcome to our family!’ will do the job. After the letter’s opening, for the bulk of it, state why you are writing the letter in an honest statement”. “I thought of writing today to say how proud I am of you.” Or maybe “I’m writing this letter for you, so you can look back on it whenever you need to as you get through this new adventure” e.” Or maybe”, “I wanted to write down anecdotes of this family on paper, so you know what has gone through the lives of the people who love you unconditionally” y.” It is just about why you are writing the letter.
Expand on after the why. Tell about the heart, a place of affection and love for the grandchildren. Don’t make it hard for yourself too much, don’t get stuck with the obsession of saying things in perfect sentences and grammar. Just be who you are, and be chatty and relaxed, like when you talk in person to them. Some people can write better than the way they talk, and if that’s true for you, imagine the conversation you wish you could have with your grandchildren, then start writing that down in the letter. There’s no ideal and proper length. Whatever you feel like you want to say, long or short, doesn’t matter. Just go for it. Use an affectionate sentence or two once you intend to wrap it up. There is no need for any excuse for quitting, sentences like “Well, it would be better for me to go!” or any apologetic sentence. State how thankful you are that you had a chance to tell about your true feelings and how much you care about your babe. You can close with a sweet statement like “I love you” or “I always think of you” or “I pray for you.” Whatever you like. At last, you can add a memorable phrase to be kept between you and your babe. It’s a wonderful way to leave a sweet mark for your grandchildren to see. Children will carry their grandmother’s signature throughout their lives, so do it neatly in your style.
