“I'm a health visitor. Here's what I wish I had time to say at the 9-month check.”

Mette has been a health visitor in Copenhagen for eleven years. At the 8–9 month developmental check, she sees each family for roughly fifteen minutes. In that time she covers motor development, language, feeding, social interaction, and — briefly, if there's time — sleep.

There is almost never enough time.

We sat with her for an hour and asked her what she'd say if there were no appointment clock.

The first thing parents ask you about at the 9-month check — is it sleep?

It's in the top three, always. The other two are feeding and whether their child is developing “normally.” But sleep is the one people bring up apologetically. They'll mention it at the end, almost like an afterthought. “Oh, and sleep has been a bit difficult.” As if they're embarrassed to say it's the main reason they were looking forward to this appointment.

I always try to signal early that it's a legitimate topic. Because it is. Sleep difficulties at this age are extremely common — in Denmark, about one in fifteen families flags a concern significant enough to note in the records at this visit. And that's just the ones who flag it. The ones who don't are often struggling just as much; they've just decided it's not something you admit.

What do you actually have time to say about sleep in fifteen minutes?

Not enough. I can ask how many times a night the child wakes. I can ask whether they can resettle independently. I can ask about nap timing and how long they've been awake before bed. And from those answers I usually have a fairly clear picture of what's happening.

But then I have about two minutes to say something useful. Two minutes to cover what might take an hour to explain properly. So I give the headline, and I give a referral if it seems serious, and I move on. And I know — I know — that the family will go home and either find the right information somewhere or spiral into a Google rabbit hole and come out more confused than when they went in.

What's the most common thing you see that parents have got wrong?

Wrong is a hard word. I prefer to say: the most common misunderstanding is about timing. Parents tend to watch the clock — “it's 7pm, so it's bedtime.” But a child's readiness to sleep isn't governed by the clock. It's governed by how long they've been awake since their last nap. That window is different for every child and changes as they develop. If bedtime happens outside that window — too early or too late — the child fights sleep, and the parent interprets that as a problem with the child rather than a problem with the timing.

I'd say sixty, maybe seventy percent of the families I see with sleep difficulties are working with a schedule that doesn't match their child's actual biology. The fix isn't dramatic. It's adjusting by thirty or forty-five minutes, in the right direction, and holding it consistently. But I can't always get to that in fifteen minutes.

What about the families who come back at eighteen months still struggling?

This is the part of my job I find hardest. I see families at nine months and I give them what I can. And sometimes I see the same family again, or I hear from a colleague who saw them at a later visit, and nothing has changed. The child is now a toddler and the parents are — I don't want to use the word broken, but sometimes that's what I see.

What I notice with those families, almost always, is that nothing was resolved early because no one had the time to go deep enough to fix it. They got tips. They got pamphlets. They read things online that contradicted each other. But they never got a complete picture of what was actually happening with their specific child, in their specific schedule, in their specific home.

Sleep problems don't tend to fix themselves. That's the thing I'd want every parent to know at nine months — not to frighten them, but to give them permission to take it seriously now rather than wait.

Is there a question you get asked that reveals the most about how a family is actually doing?

Yes. It's this one: “Is it normal to feel like this?”

They're not asking about the baby anymore when they ask that. They're asking about themselves. About the anger they felt at 3am when the baby woke for the fourth time. About the resentment they feel toward their partner. About the thought they had — the one they won't say out loud — that they weren't sure they could keep doing this.

When someone asks me that, I always make time. Whatever else is on the appointment agenda, I make time.

And I wish I had forty-five minutes to tell them all of them.
