I used to lie awake between wake-ups doing the maths.

Two hours since the last one. Which meant another one was probably coming in forty minutes. Which meant I had maybe thirty minutes of actual sleep ahead of me if I fell asleep right now. Which I wouldn’t, because I was doing the maths.

This went on for four months. And the whole time, I was convinced I was doing something wrong.

I’d read the books. I’d tried the routines. I’d moved bedtime earlier, then later. I’d tried white noise, no noise, a nightlight, complete darkness. I’d asked my mum, my sister, my health visitor, the moms in my online group. Everyone had an opinion. Nobody had an answer that worked for us.

The thing that finally helped wasn’t a new tip. It was understanding what was actually happening.

WHY BABIES WAKE UP (AND WHY IT IS NOT YOUR FAULT)

Here is what I wish someone had told me in those first bleary weeks.

Babies sleep in cycles, just like we do. Each cycle lasts about 45 minutes. At the end of each one they surface briefly to light sleep before going back under. Adults do this too — we just don’t fully wake up because we’ve learned to transition between cycles on our own.

Babies haven’t learned that yet. And here’s the part that changed everything for me: at that 45-minute surface point, a baby’s brain looks for whatever was there when they first fell asleep. If you were holding them, they look for your arms. If they fell asleep feeding, they look for the feed. If they fell asleep with you next to them, they look for you. When it’s gone, they cry. Every time, all night, like clockwork.

It’s not a sleep problem. It’s an association. And once you understand that, you know exactly what needs to change — and what doesn’t.

WHAT ACTUALLY HELPED OUR FAMILY

Once I understood the mechanism, everything else fell into place. We didn’t overhaul our entire routine overnight. We just changed one thing: what happened in the last ten minutes before our daughter fell asleep.

Instead of feeding her to sleep and then carefully transferring her to the cot (and holding our breath every single time), we moved the feed earlier in the bedtime sequence. She was still fed, still full, still settled. But she was awake when she went down. The cot became the last thing she knew before sleep. So when she surfaced at 45 minutes, the cot was still there. She didn’t need us to recreate the conditions. She could find her own way back.

It didn’t work perfectly on Night 1. Night 3 was genuinely hard. But by Night 5 she was sleeping in stretches that felt almost unbelievable after months of the alternative.

The tool that helped us put this together was hellolunio.com. It asked us five questions about our daughter’s specific pattern and gave us a routine built around her, not a generic method. For families who need more, there is also Nora Live, a virtual sleep consultation available the same night with no waiting list and no three-week appointment delay. A real 25-minute voice session that identifies exactly what is going on and delivers a personalised five-night plan. Then Nora stays available by chat for five nights after, so you are not on your own when Night 3 hits and everything feels like it is falling apart. That specificity and that support was what had been missing from every other thing we had tried.

YOU ARE NOT FAILING

If you are in the thick of it right now, reading this at some ungodly hour while you wait to see if they’ll stay down — I want you to know that the exhaustion you’re feeling is real and measurable and documented. Studies tracking parents through the first year show sleep deprivation at this level affects memory, emotional regulation, and relationships in ways that go far beyond just feeling tired.

You are not weak. You are not doing it wrong. You just haven’t had the right information for your specific baby yet.

That’s a solvable problem.
