The bond between a grandparent and a grandchild can be one of the strongest a person ever has, and the curious part is that it rarely happens by accident. The grandparents who end up genuinely close to their grandchildren, the ones those grandchildren actively choose to visit once they’re grown, tend to do a particular set of things, mostly without ever realising they’re doing them.

I know, because I had grandparents like that. The bond I had with mine was, and remains, one of the great fortunes of my life, and looking back I can see precisely what they did to build it. None of it was complicated. All of it counted. These are ten of the habits that made the difference.

1. They gave you their unhurried time

The first and biggest one. Parents, however loving, are usually busy, distracted, halfway through something else. Grandparents, the retired ones especially, have the single resource children crave most and adults ration hardest, which is unhurried attention. My grandfather never once seemed to be in a rush when I was around. An afternoon with him stretched out with no particular end to it, no clock, no next appointment to get to, and a child registers that instantly. Being handed someone’s unhurried time is, to a kid, almost indistinguishable from being loved.

2. They took you seriously as a person

The ones who build real bonds treat a child as a small person with genuine opinions, not a cute pet to be cooed at. They ask real questions and they listen to the answers. My nan asked me what I made of things, properly, from when I was tiny, and waited for my answer as though it carried weight. Nothing makes a child love an adult faster than being taken seriously by one. It is rarer than it ought to be, and children never forget who did it for them.

3. They had a ritual that was just yours

The strong bonds nearly always have something that belongs to the two of you alone. A standing activity, a shared project, a place you went together. With my grandfather it was his allotment, where I was handed a trowel and a patch of my own before I was tall enough to see over the runner beans. With my nan it was the baking, the pair of us up to our elbows in flour every Saturday. The activity itself barely matters. What matters is that it was ours, repeated, dependable, a small private world with a population of two.

4. They told you the stories

Bond-building grandparents are the keepers of the family’s history, and the good ones hand it down. They tell you where you came from, who your people were, what your great-uncle got up to in the war and which relative once did something that scandalised the entire street. My grandfather’s stories gave me a sense of being part of something far longer than myself, a line running back well beyond me, and that turns out to be among the most grounding gifts a child can receive. A kid who knows the family stories knows they belong to something.

5. They were a judgment-free zone

Parents are obliged to discipline, correct, worry and enforce. Grandparents get to be the soft place to land, and the wise ones use that licence beautifully. My grandparents’ house was the one place where I felt I could be entirely myself without being pulled up for it, a spot of faintly conspiratorial alliance against the general unfairness of being small. Every child needs one adult who is simply and unmistakably on their side, no conditions attached, and for me that was the two of them.

6. They let you be genuinely useful

There’s a difference between handing a child busywork to keep them quiet and letting them do something real, and the best grandparents go for the second. On the allotment I was never given a pretend job. I was given actual work, digging, watering, hauling things about, the sort a child can take real pride in because it genuinely mattered. Being trusted with something that counts, by an adult you look up to, builds a kind of confidence that praise on its own never manages. They made me feel capable, which is its own quiet form of love.

7. They taught you things with their hands

The bond-builders tend to be teachers of the practical kind, the ones who show rather than tell. How to plant, how to mend, how to do the small competent jobs that make a person feel able in the world. My grandad taught me to fix things, patiently, letting me get it wrong and try again without once making me feel foolish for not knowing. Every skill a grandparent passes down is also a few more hours spent side by side, and the bond gets built inside the teaching, almost as a by-product of it.

8. They remembered the small details about you

The ones who stay close are the ones who actually keep track. They remember whatever you’re obsessed with this month and ask about it next time, know your favourite biscuit and your current best friend’s name. My nan remembered everything, every passing enthusiasm I ever had, and would ask after it weeks later as though she’d been turning it over in the meantime. Being remembered in that kind of detail tells a child they are held in someone’s mind even when they’re nowhere in the room, and that is an enormous gift to give a person.

9. They showed up the same way every time

Reliability is its own variety of love, and children feel it keenly. The grandparents who build unbreakable bonds are predictable in the finest sense, there every Sunday, the same welcome, the same warmth, a fixed point you could set your week by. There was never the slightest doubt, with mine, that they would be pleased to see me. That certainty, repeated across years and years, settles into a kind of bedrock a child carries with them into the whole of their later life.

10. They simply delighted in you

Above every other habit, the strongest grandparents make a child feel actively delighted in, enjoyed rather than merely loved out of duty, as though your arrival were the best part of their week. My grandparents lit up when I came through the door, every single time, and a child reads that the instant it happens and never forgets the feeling of being someone’s favourite person to see. To be delighted in, with no conditions attached, may be the finest thing one human being can offer another, and grandparents are uniquely well placed to offer it.

What it all comes down to

The thread running through all ten is really just attention, the unhurried, delighted, dependable attention that says, without ever needing to be spoken, you matter to me exactly as you are. Children can’t always put it into words, but they feel the gap between an adult who is truly present and one who is merely nearby, and they remember which they were given for the rest of their lives.

My grandparents are gone now, but the bond they built has not gone anywhere at all, which is the surest test of whether a thing was ever truly unbreakable. I still carry the allotment and the flour and the stories and the flat certainty of being delighted in, and I expect to carry them as long as I last. That is what these habits really build, and it endures. A close grandchild first, and then an adult who spends the rest of his days grateful for it, and who fully intends to pass that attention on when his own turn finally comes around.
