34 Weeks Pregnant: The Week Your Baby Learns How to Feed

Last week, your body began arming your baby with your immunity. This week, your baby starts rehearsing the very first thing the two of you will do together once they arrive. Feeding.

Welcome to week thirty-four. Your baby is practising the delicate rhythm of feeding, building up a protective coat for the journey out, and rounding into the soft little newborn you are about to meet. Let me show you.

Your baby is learning how to feed

Your baby has been sucking on their thumb and swallowing little sips of fluid for weeks now. But this week, something important clicks into place. They begin putting it all together into the single most useful skill of their first day. Feeding.

Feeding looks simple, but it is not. To do it safely, your baby has to coordinate three separate things in perfect order, suck, then swallow, then breathe, over and over, without ever muddling them up. And right around now, that coordination matures. Your baby practises the rhythm again and again, in the dark, perfecting it long before there is any milk to drink.

It is such a vital skill that babies born much earlier than this often need a little help with feeding at first, simply because the rhythm has not quite come together yet. But your baby is rehearsing it now, getting ready. So that when they are finally placed against you, and guided by the scent of you they already know, they can root, latch, and feed, knowing just what to do.

A protective coat for the journey

Something else is building up this week too, a creamy white layer called vernix.

This waxy coating has been protecting your baby's skin from months of soaking in fluid, keeping it soft rather than wrinkled and waterlogged. Now it thickens, and it has one more job to do. When the time comes, it will help your baby slip more smoothly and gently into the world.

Some babies are born still wearing a good coating of it. If yours is, there is no rush to wipe it all away. That little white coat is doing good work, soothing and protecting their brand new skin.

How big is my baby at 34 weeks?

Around forty-five centimetres now, head to heel, and roughly two and a quarter kilograms. Your baby is soft and round, their skin smooth, their cheeks filling out, looking more and more like the newborn you will soon be holding.

Plump, practised, and very nearly ready.

What is happening in my body?

You are well into the home stretch now, and likely feeling every bit of it.

Your bump is large and heavy, sleep is precious and hard-won, and you may be dealing with backache, swollen feet, or breathlessness. Some mothers also start to notice their breasts leaking a little colostrum around now, the rich first milk, a sign your body is getting ready to feed your baby too. It is completely normal, whether it happens for you or not. Keep resting where you can, lean on your people, and stay in close touch with your midwife about how you are feeling and how your baby is moving.

From Courtney. This is the one that gets me as a lactation consultant, every single time. People imagine babies have to be taught to feed, but the truth is your baby is already practising, right now, in the dark. Suck. Swallow. Breathe. Over and over, getting the rhythm just right, weeks before they will ever need it. And when they are finally laid on your chest, that practice, together with the scent of you they already know, is what guides them, bobbing and rooting, to find the breast all on their own. It is one of the most extraordinary things I have ever watched. So if you are nervous about feeding, please hear this. Your baby has been getting ready for it for a very long time. And so, in your own quiet way, have you, mama.

The one thing to do this week

This week, with your baby rehearsing for that first feed, it is a brilliant time to do a little learning of your own, while you still have the time and space to take it in.

There is no right way to feed, only your way, breast, bottle, or a mix of both. But whichever you choose, a little knowing-what-to-expect ahead of time takes so much of the fear out of those early days. And the same goes for understanding what newborn sleep is really like, before you are living it at 3am. Going in informed genuinely helps. It is the difference between panicking and thinking, ah, I know this.

That is exactly why I made the Prep for Baby course in the Mama Years app, walking you through feeding, recovery, and newborn sleep. It is broken into short, bite-sized videos, most only a few minutes long, so you can watch one whenever you have a spare moment, feet up on the sofa or curled up in bed. Under an hour all up. Do it now while you comfortably can, and you will thank yourself later. Then rest, mama. You are doing so well.

Coming up in week thirty-five

Next week, your baby pours their energy into growing, piling on soft baby fat by the day and rounding out into the squishable little newborn you are about to meet. Their brain, too, is growing faster now than at almost any point yet, adding folds, wrinkles, and brand new abilities.

Week thirty-five is where your baby really starts to fill out. I will see you there.
