26 Weeks Pregnant: The Week Your Baby Opens Their Eyes

Last week, your baby's brain began to fold into the shape of a true human mind. This week, the very last of your baby's senses switches on. Your baby opens their eyes.

Welcome to week twenty-six. After months sealed shut in the dark, those little eyelids lift for the first time, your baby begins to blink and sense light, and the pigment that will one day colour those eyes starts to appear. Let me show you.

Your baby opens their eyes

Something quietly momentous happens this week. Your baby opens their eyes.

Their eyelids have been fused tightly shut since around week ten, protecting the delicate eyes while they formed. Now, somewhere around now and over the next couple of weeks, those lids gently unseal and lift for the very first time. Your baby begins to blink, and to open and close their eyes, in the dim, rosy light of your womb.

This is the last of your baby's senses to arrive. Touch came first, way back in the early weeks. Then taste, then smell, then hearing. Sight has waited until nearly the end, and now, at last, it joins them. Once those eyes are open, your baby can begin to sense light and shadow, dim and blurry for now. Shine a soft light on your bump and your baby may notice the glow, and turn or kick towards it.

But here is the part that undoes me. Right now, your baby's eyes can only focus a short distance, and they will still be that way at birth, able to see most clearly something about twenty to thirty centimetres from their face. That is the exact distance from your breast to your eyes when you cradle your baby in to feed. And of everything in the whole bright, busy world, the thing a newborn most wants to look at is a face. Your baby's eyes are being made, this very week, to find yours first.

The first hint of colour

Your baby is also starting to make melanin this week, the pigment that gives skin, hair, and eyes their colour.

For now, those new eyes have very little colour in them. And here is something many parents do not know. Even at birth, your baby's eye colour may not be settled. Lots of babies arrive with blue or grey-blue eyes that gradually deepen and change over their first year, as more pigment fills in. So the eyes opening this week are not quite their final shade just yet. That is a surprise being saved for later.

How big is my baby at 26 weeks?

Around thirty-five to thirty-six centimetres now, head to heel, and roughly seven hundred and sixty grams. Your baby is steadily plumping up, the skin smoothing out, and getting more cramped for space, so the kicks and rolls are strong and easy to feel.

Eyes open, ears listening, and busy as ever in there.

What is happening in my body?

You are coming to the end of the second trimester, with the third, and your baby, drawing closer.

Your growing uterus is pressing on more of you now, which can mean a sore back, a little breathlessness, or trouble getting comfortable at night. All very normal. You might also feel your baby's movements as full rolls and visible kicks that someone resting a hand on your bump can feel too, which is a lovely thing to share. As always, flag anything that worries you to your midwife or doctor, and rest as much as your body asks for.

From Courtney. Of all the milestones, this is one that makes me well up. Sight is the very last of your baby's senses to arrive, after touch and taste and smell and hearing, and this week it finally switches on. Those eyes, sealed shut for months, open into the soft, rosy dark. And here is the part I can hardly bear, in the best way. When your baby is born, their eyes will focus best at a distance of about twenty to thirty centimetres. That is, almost exactly, the distance from your breast to your face when you hold them in to feed. Your baby's eyes are being built, right now, to find you first. Of all the faces in all the world, yours is the one they are getting ready to look for. Talk about made for each other, mama.

The one thing to do this week

This week, here is a gentle little game you can try if you fancy it. In a dim room, when your baby is having an active spell, try shining a soft light, your phone torch is perfect, onto your bump for a few seconds. Some babies will stir, shift, or give a little kick, curious about the glow. Others will not do a thing, and that is completely fine too, so please do not read anything into it either way.

It is simply a sweet way to say hello to those brand new eyes. And then, as always, rest your own eyes whenever you need to.

Coming up in week twenty-seven

Next week, you step into the third trimester, the final stretch before you finally meet your baby. Their brain is busier than ever, and your baby may now pick out the sound of your voice from any other, growing calm and familiar with the people they will be born to love.

Week twenty-seven begins the home straight. I will see you there.
