You are standing sideways in front of the mirror, doing the thing we all do. Turning slightly. Smoothing your top down. Wondering why, months after your baby arrived, your tummy still looks like it is holding something.
Maybe someone has asked. Maybe nobody has, and that is somehow worse, because you are still asking yourself.
Here is what I want you to know before you read another word: that soft, doming, still-pregnant-looking middle is very often not fat, and it is almost never a discipline problem. It is a real, physical, measurable thing called diastasis recti. And you can check for it yourself, on your bedroom floor, in about two minutes.
No appointment. No gadget. Just your own hands and a little curiosity.
So what actually happened in there?
Run your fingers down the middle of your stomach, from the bottom of your ribs to your pubic bone. Underneath that line sits a band of connective tissue called the linea alba. It is the seam that joins the two long strips of your "six-pack" muscles together.
When you are pregnant, that seam has a job to do. It softens and stretches sideways to make room for a growing baby. It is supposed to. A body that refused to do this would be a body in trouble.
After birth, the seam starts drawing back in on its own. Most of that happens in the first eight weeks, and then the pace slows right down. Which is exactly why so many of us hit three, six, nine months and feel stuck: the fast part is over, and the slow part needs help rather than time alone.
So it is common. Somewhere between two-thirds and nearly all women have some separation by late pregnancy. Around six in ten of us still have it after birth, and roughly a third are still living with it a year later.
Read that again if you need to. You are not the one mum whose body did something odd. You are in the majority, and most of the majority has never been told what to look for.
The two-minute check
You need a flat surface and bare skin on your tummy. That is the whole list. Do it in the morning if you can, before your middle has had a full day of food and gravity.
-
Lie on your back,
knees bent, feet flat on the floor, head resting down.
-
Place two or three fingers just above your belly button,
flat, pointing down towards your toes.
-
Press gently in.
Not a poke — a slow, curious press, like you are testing whether bread has risen.
-
Lift your head just slightly,
chin tucked, as if you are peeking at your toes. Shoulders barely leave the floor. This is not a sit-up.
-
Feel what happens under your fingers.
You are looking for two things: how wide the gap is, and how deep your fingers sink before the tissue pushes back.
-
Lower your head and move your fingers,
then repeat at two more places: right at your belly button, and about three finger-widths below it.
-
Write down what you found.
Three numbers, three spots. Above, at, below.
That is it. You have just done what a physio does in the first two minutes of an assessment.
One gentle caution: this is a check, not a verdict. Do not repeat it every morning. Tissue changes slowly, and checking daily will only make you anxious about numbers that were never going to move that fast. Every three or four weeks is plenty.
Reading what you felt
Most articles stop at the gap. Please do not.
Width is the easy bit. Count the fingers that fit side by side, snugly, without forcing. One finger, two, three, four. Roughly a finger is a centimetre, and most clinicians start paying attention at around two centimetres, which is roughly two fingers.
Depth is the part that actually matters. When you lifted your head, did your fingers sink into a soft, squashy hollow that seemed to have no floor? Or did something spring up underneath them — a trampoline rather than a hammock?
That springiness is tension in the linea alba, and current thinking in postpartum rehab is that building tension back into that tissue matters more than closing the gap completely. A four-finger gap with good spring is often a more functional tummy than a two-finger gap that swallows your hand.
So you are really answering these questions:
Width — how many fingers fit, snugly. Note it as 1, 2, 3 or 4+ fingers.
Depth and spring — whether the tissue pushes back. Note it as springy, soft, or no floor.
Where — above, at, and below the navel. Three separate readings.
And while you are down there, one more thing worth noticing: when you lifted your head, did the middle of your tummy dome up into a little ridge, like a loaf? That doming is your body telling you which movements it is not ready for yet. File it away. It becomes useful in a minute.
What your result means
A finger or less, with good spring underneath: that is a normal, healthy midline. Nothing to fix.
Two fingers with decent tension: extremely common, especially in the first year. Worth doing focused core work, not worth losing sleep over.
Three or more fingers, or a gap that feels soft and bottomless at any of the three points: this is worth having someone look at properly. Not because something is wrong with you, but because guided rehab will get you further than guessing from a blog post — including this one.
Please book a pelvic health physio, rather than working through it alone, if any of these are true:
- Your fingers sink in with no floor, however wide or narrow the gap
- You are leaking urine when you cough, sneeze, laugh or run
- You feel heaviness, dragging or bulging in your pelvic floor
- Your lower back or pelvis aches through ordinary days
- You can see a bulge along your midline when you sit up or lift your baby
- You have pain, or a tender lump near your navel that does not soften
That last one matters. Pain and a firm lump can point to a hernia rather than a simple separation, and that is a doctor's job, not a Pilates video's.
And if you are reading this with a five-year-old and a full year of "I should have sorted this out by now" — you have not missed the window. There isn't one. Tissue responds to loading at three months postpartum and it responds at three years postpartum.
What to do with what you found
You do not need a programme today. You need three habits, and they cost you almost nothing.
Breathe before you brace. Inhale and let your ribs widen. Exhale slowly, and as you do, feel your lower tummy draw gently inwards and upwards — as if you were easing into jeans that are slightly too tight. That is your deep core switching on. Ten of those, while the kettle boils, is a legitimate session.
Exhale on the effort. Standing up, lifting the car seat, hoisting a toddler onto your hip — breathe out as you do the hard bit. Holding your breath pushes pressure straight down the middle at exactly the moment you need it held.
Roll to your side to get up. Every time. From the bed, from the couch, from the floor. Sitting straight up is a crunch, and you do about fifteen of them a day without noticing.
From there, progress is simpler than it sounds. You keep that same exhale-and-draw-in, and you ask it to hold under slightly harder work each week. Breathing on its own. Then breathing while you slide one heel along the floor. Then while you lift a knee. Then while you stand up holding a toddler.
The signal that tells you when you have gone a step too far is the one you noticed earlier: if your tummy domes up into a ridge along the midline, that movement is too much for today. Back off one step, keep the exhale, and try it again in a fortnight. Crunches, sit-ups and long planks tend to be the first things to dome and the last things to help, so leave those be for now.
Before you get up off the floor
Whatever number you just counted, I want you to hold one thought alongside it.
That seam down the middle of you stretched because it was asked to. It made room. It is the reason there is a person asleep down the hall, or yelling from the bath, or currently attached to you.
A gap is not damage. It is evidence.
So write your three numbers somewhere you will find them again, put a note in your diary for four weeks' time, and leave it alone in between. Then start with those three habits and let your body do the quiet work in between — gently, and in the time you actually have.
This article is general information, not medical advice. If anything you found today worried you, or if you have pain, please see your doctor or a pelvic health physiotherapist.
