If you’ve been poking at your belly lately trying to figure out whether that hard lump is a head or a butt, belly mapping might be your new favorite pregnancy activity. It’s an at-home method developed by Gail Tully of Spinning Babies, and it uses what you can see and feel from the outside to piece together which way your baby is lying. It won’t replace an exam or an ultrasound, but it can help you make sense of all those kicks, rolls, and random pokes to the ribs.
I’m going to walk you through when babies usually turn head down, what the different positions actually mean, how to belly map step by step, and the most common signs that your baby is head down. I’ll also cover what your options are if your baby is still breech as your due date gets closer. But first, so you can read the rest of this with your shoulders a little lower: most babies get head down on their own. Belly mapping is a way to get to know your baby, not one more thing to stress about.

What is belly mapping (and does it actually work?)
Belly mapping is basically detective work. You notice where you feel kicks, wiggles, hiccups, and firm or rounded parts, then you draw those clues onto your belly (yes, literally) or onto a piece of paper. Once you have a rough “map,” you can make an educated guess about where your baby’s head, back, arms, and legs are.
So does it work? It can be really useful, especially in the last couple of months of pregnancy, when your baby is big enough that the individual parts are easier to tell apart. But it’s an estimate, not a diagnosis. Even experienced providers can misjudge position by touch alone, which is exactly why an ultrasound gets used when position REALLY matters, like close to your due date or when a breech baby is suspected. I think of belly mapping as a way to understand your baby better and to walk into your appointments with better questions. It’s not meant to give you a final answer.
When do babies turn head down?
This question is on a LOT of minds in the third trimester. So many people reach out to me when they hit their third trimester and find out their baby is breech, and they’re understandably a little freaked out.
If that’s you, take a breath. Babies move around a ton during pregnancy, and many babies who are breech in the late second or early third trimester flip head down on their own. The share of breech babies drops steadily as pregnancy goes on. Around 28 weeks, something like 1 in 5 babies is breech, but by term only about 3 to 4 out of every 100 still are. So the large majority of babies end up head down by the time they’re full term, without anyone doing anything special.
And for the small number who stay breech, there are still safe ways forward. Depending on your situation, that might mean trying to turn the baby with a procedure called an external cephalic version, planning a cesarean birth, or in some settings, having a vaginal breech birth with a provider who’s experienced in it. Your provider will help you figure out which options make sense for you.
If baby is head down at 32 weeks, will they stay that way?
Usually, yes. Most babies who are head down in the third trimester stay head down, and as your baby grows, there’s just less room for big acrobatics. It’s still possible for a baby to change position after that, which is why your provider will keep checking at later appointments, especially from around 36 weeks on. Head down at 32 weeks is a great sign. It’s just not a guarantee.
Baby’s position, explained
“Head down” is only part of the story. Providers also describe which direction the back of your baby’s head (the occiput) is facing, which is how you end up with mysterious abbreviations like LOA or ROP in your chart. There are quite a few specific variations, but these are the main ones worth knowing:
Occiput anterior (OA): Baby is head down and facing your back, with the back of their head toward the front of your belly. This is generally considered the most favorable position for a vaginal birth, because it lets baby tuck their chin and fit through your pelvis most easily.
Occiput posterior (OP): Baby is head down but facing your belly, with the back of their head against your spine. You’ll also hear this called “sunny side up.”
Occiput transverse (OT): Baby is head down and facing one of your hips.
And if your baby isn’t head down, they’re usually in one of these:
Breech: Baby’s bottom or feet are positioned to come out first, and their head is up near your ribs.
Transverse lie: Baby is lying sideways across your uterus.
Why baby’s position matters
Before labor, position mostly matters for planning. If your baby is still breech or lying sideways near your due date, that usually leads to a conversation with your provider about trying to turn the baby or planning a cesarean birth. A baby who stays sideways can’t be born vaginally, so that one isn’t really optional.
During labor, position can affect how things go. A baby who stays OP is associated with longer labors and a higher chance of needing help with delivery, like a vacuum, forceps, or a cesarean. It’s also often linked with more back pain (yes, “back labor” is a real and very unfun thing), although not everyone with an OP baby has it. That said, plenty of babies who start labor OP or OT rotate to OA on their own as labor goes on and are born without any drama at all.
I’ve been through this one personally. During my second birth, my labor stalled because my guy was OP. If you find yourself in the same spot, changing positions often can help encourage your baby to rotate, and your nurse can help you find positions that actually work for you. And if reading about labor positions has you wanting the bigger picture of what actually happens in labor, my free mini birth class is a good place to start.
How to belly map, step by step
When to start belly mapping
Belly mapping tends to be easiest in the last couple of months of pregnancy, once your baby is big enough that you can tell the parts apart. Before that, babies have so much room to move that your beautiful map might be completely wrong by the next day. It usually helps to try when your baby is active, with an empty bladder, while you’re lying back slightly propped up. And if your placenta is on the front wall of your uterus (an anterior placenta), it can cushion kicks and make your baby harder to read, so don’t take a confusing map personally.
Here’s a simplified version of the method, adapted from Gail Tully’s free parent handout at Spinning Babies (full credit to her!):
Get to know your baby’s movements. Spend a few days just paying attention to how your baby moves before you try to map anything. If you’re already doing daily kick counts, you’ve got a head start. Notice the difference between sharp kicks or jabs, slow rolls or stretches, and tiny flutters.
Grab a washable marker or a piece of paper. You can draw right on your belly, or draw a circle on paper, divide it into four sections, and mark what you feel and where you feel it.
Find your baby’s head. It feels like a firm, round ball, kind of like a small bowling ball. If your baby is head down, you’ll usually find it low, just above your pubic bone. If it’s up under your ribs instead, your baby may be breech. Always press gently. You’re feeling, not kneading bread.
Figure out which way baby is facing. Once you’ve found the head, start thinking about which way the rest of the body is turned. Spinning Babies suggests using a doll or stuffed animal to help you picture the position, which sounds silly until you’re trying to rotate a baby in your head and realize how hard that is.
Find your baby’s back. The back usually feels like a long, firm, smooth curve along one side of your belly. If you can feel it clearly on your left or right, your baby may be in an anterior position on that side. If you can’t find a clear back and instead feel lots of little parts in the front, your baby may be posterior.
Notice where the kicks land. Strong kicks usually come from the feet, so where you feel them tells you where the legs are. Kicks up under your ribs on one side often fit with a head-down baby whose back is on the opposite side. Kicks and wiggles across the front of your belly can point to a posterior baby.
Watch for small movements near the head. Little flutters or scratchy movements low in your belly, near the head, are often your baby’s hands. These can give you extra clues about which way they’re facing.
Once you’ve marked the head, back, kicks, and hands, step back and look at the whole picture. Does it make sense as one baby? If it looks more like a Picasso, that’s completely normal. Try again another day, or bring your map to your next appointment and ask your provider what they think. And if you want to hear about belly mapping straight from the source, I talked with Gail Tully herself about it on the podcast.
Signs your baby is head down
There’s no single sign that confirms position, but several of these together can point to a head-down baby:
Strong kicks up high. You feel them near or under your ribs rather than low in your belly or down toward your cervix.
Hiccups down low. Your baby’s hiccups often show up as little rhythmic bumps in your lower belly, below your belly button.
A firm, round shape just above your pubic bone. This is often the head, especially later in pregnancy as it starts settling into your pelvis.
Pressure low in your pelvis. Hello, constant need to pee.
A smooth, firm curve along one side. That’s often your baby’s back.
And what about belly shape? You’ll find SO many claims online about what a head-down belly “looks like,” but bellies vary so much from person to person (and pregnancy to pregnancy) that shape alone really isn’t a reliable way to tell your baby’s position.
How a breech or transverse baby may feel different
With a breech baby, you might feel a hard, round head up near your ribs (sometimes very much up in your ribs), kicks low in your belly or toward your bladder, and hiccups higher up. With a transverse baby, you may feel firm parts on both sides of your belly, head on one side and bottom on the other, with movement across the middle. These are clues, not a diagnosis. If you think your baby isn’t head down, especially as you get closer to term, mention it to your provider so they can check.
How your provider confirms baby’s position
At prenatal appointments, your provider often checks position by feeling your belly with their hands, using a set of steps called Leopold’s maneuvers. They may also listen for the heartbeat, which is often loudest below your belly button when baby is head down. If there’s any question, especially in the last few weeks of pregnancy or once you’re in labor, a quick ultrasound gives a clear answer.
What if baby isn’t head down?
If belly mapping, an exam, or an ultrasound shows that your baby isn’t head down (or isn’t in that ideal OA position), there are options to talk through with your provider. (I also answered a bunch of breech questions on the podcast, including whether breech tends to happen again in a future pregnancy, if you want to go deeper.)
Spinning Babies resources
Spinning Babies has a lot of free information on positioning, plus a paid ebook called Helping Your Breech Baby Turn for people dealing with a breech baby. Lots of parents find these resources really helpful, and it can feel good to have something to actually DO. Just know that research on whether specific positions or exercises turn breech babies is limited, so use them alongside your provider’s guidance rather than instead of it.
The Webster Technique
Some people see a chiropractor trained in the Webster Technique, a pregnancy-specific approach to adjusting the pelvis and the muscles and ligaments around it. Some families have good experiences with it, but there isn’t strong research showing that it turns breech babies. If you’re interested, check with your provider first, and pick a chiropractor who has experience caring for pregnant patients.
External cephalic version (ECV)
An external cephalic version is a procedure where your provider uses their hands on the outside of your belly to try to turn your baby head down. It’s usually offered from 36 weeks on, in a hospital where your baby can be monitored before and after, and where a cesarean can happen quickly if it’s ever needed.
On average, an ECV works a little over half the time. Success depends on things like whether you’ve given birth before, how much fluid is around your baby, and where your placenta is. It’s not right for everyone, and while serious complications are uncommon, it does carry some risks, so it’s worth having a real conversation with your provider about whether it makes sense for you.
And if your baby ends up staying breech and a cesarean becomes the plan, my Birth It Up course includes a whole C-section series to help you feel ready for that birth, too.
When to call your provider
Belly mapping should be gentle and kind of fun. Stop if anything hurts, and don’t push hard on your belly. If you notice your baby moving less than usual, call your provider right away. Don’t wait to see whether a map or a kick count looks better later. You should also call if you have pain, bleeding, leaking fluid, or regular contractions before 37 weeks, or if you think your baby might be breech as you get close to your due date.
Wrapping up
If you take one thing from all of this, I hope it’s that you don’t need to stress about your baby’s position weeks before your due date. Most babies sort themselves out, and the ones who don’t still have safe options.
In the meantime, belly mapping is a pretty great excuse to lie on the couch, draw on yourself, and get to know the tiny person who keeps kicking you in the ribs. Bring what you find to your next appointment and let your provider fill in the rest.
