Why Your Baby Won't Sleep Probably Has Nothing to Do With Sleep

There's a scenario I hear constantly from the mums who find me, and it goes something like this. She has tried everything. The apps, the books, the Google spirals at 2am, the advice from the mothers' group, maybe even another sleep consultant at some point. She's tried earlier bedtimes and later ones. She's done different settling methods. She's read about regressions and wake windows and sleep associations until her eyes cross. And still, nothing sticks. Still, the nights are fragmented, the naps are a disaster, and she is so far past exhaustion that she can't remember what it felt like to not be tired.

And she genuinely doesn't understand why. Because she's done everything right.

Here's what I want to offer her, and maybe you, if this sounds familiar. Sometimes the reason nothing is working is that the thing you're trying to fix is not actually the thing that's broken.

What parents think is happening

When a baby won't sleep, the instinct is to look at sleep. How they're falling asleep, what associations they have, whether the schedule is right, whether they need to learn to "self settle." And all of those things do matter and are absolutely worth looking at. But when a family comes to me having already tried all of that with no meaningful change, my first question is not "what settling method have you used?" My first question is "what else might be going on that we haven't looked at yet?"

Because for a meaningful number of the families I work with, there is something else going on.

The things that get missed

Before I touch a single element of a sleep plan, I run through a checklist of things I need to rule out, and some of them surprise people.

Is your baby mouth breathing during sleep? This is something parents often write off as a quirk or assume is just how their baby breathes, but consistent mouth breathing at night is a genuine red flag for enlarged tonsils or adenoids, both of which are incredibly common in young children and both of which cause exactly the kind of fragmented, restless, overtired sleep that brings families to a sleep consultant in the first place. If your child is a regular mouth breather during sleep, a GP visit and likely an ENT referral is the place to start, not a new settling method.

Is there snoring, gasping, or very sweaty restless sleep? Obstructive sleep apnoea in children is more common than most parents realise, and it gets overlooked regularly because snoring can seem normal when it's actually a sign that a child's airway is being repeatedly disrupted throughout the night. A child who snores regularly, seems exhausted during the day despite sleeping for reasonable hours, is hyperactive or irritable, or wakes repeatedly for no obvious reason needs to be assessed before any other sleep work begins.

Is there a lot of restlessness, leg movement, or complaints of growing pains at night? There is a well established connection between iron deficiency and disrupted, restless sleep in babies and young children, with research suggesting that low iron in infancy can lead to persistent sleep problems that carry through into childhood. If your baby is reliably unsettled at night despite everything else being in place, asking your GP for a full blood panel is genuinely worth doing.

Is your toddler showing daytime behaviour that looks like hyperactivity, difficulty focusing, or emotional dysregulation? Sleep deprivation in children mimics ADHD so closely that the two are regularly confused, and the conversation about diagnosis should always come after sleep has been properly assessed and addressed.

What this means for you practically

If any of the above sounds familiar, please start there, with your GP, before you try another settling approach. Because if there's something medical sitting underneath the sleep problem, no amount of work on schedules and associations and wind down routines will fix it. You'll keep trying things, they'll keep not working, and you'll keep wondering what you're doing wrong. And you won't be doing anything wrong. You'll just be working on the wrong layer.

This is what holistic sleep consulting actually means in practice. Not a softer approach to settling. Not a gentle version of sleep training. It means treating sleep as the outcome of everything else, and looking at everything else first: feeds, health, environment, schedule, temperament, mum's wellbeing, household dynamics. When the right foundations are in place across all of those areas, sleep follows naturally. And when they're not, no settling method will carry the weight of what those foundations should be doing.

If you're in Melbourne or anywhere in Australia and you've been stuck in the cycle of trying things that don't stick, I'd love to talk. I work with families through a comprehensive holistic sleep process, and it starts with a free 15 minute chat, just a chance for you to talk through what's going on and for me to listen, with no pressure and no agenda beyond that real conversation.

Because the answer to your baby's sleep probably isn't a better technique. It's a better picture of the whole thing. And that's exactly what we build together.
