For the waiting and wondering
Boy or Girl? The Old Wives' Tales Every Family Loves to Guess With
By Baby Riddle, curated with intention, always.
There is a particular kind of magic that happens somewhere around the second trimester. You feel the first real flutters. The bump finally looks like a bump. And suddenly, everyone in your life, your mother, your coworker, the woman in line at the grocery store, has an opinion about whether you are having a boy or a girl.
They will tell you it is the shape of your bump. The way you are carrying. What you have been craving at 9pm on a Tuesday. They are, of course, guessing. But it is the kind of guessing that has been passed down for generations, whispered between grandmothers and daughters, tested at baby showers, and argued about good-naturedly by families all over the world.
At Baby Riddle, we love this part of pregnancy. Not because any of it is scientifically reliable (we will get to that), but because it is playful, communal, and deeply human. Long before ultrasounds and gender reveal parties, families found ways to wonder together about the little one on the way. We think that is worth celebrating, even now, with all our modern technology.
So we pulled together the most beloved old wives' tales for gender prediction, the ones you have probably already heard at a baby shower or two, along with an honest look at what the research actually says. Use this as what it is: a sweet, low-stakes way to pass the time while you wait to meet your baby.
The tradition
Why We All Love a Good Old Wives' Tale
Before there was a fifty-fifty odds and an anatomy scan to look forward to, there was watching, noticing, and storytelling. Every culture developed its own signs. A grandmother in one country might swear by the shape of a bump. A grandmother in another might swear by the position of a wedding ring on a string. None of it was medical. All of it was love, curiosity, and the very human desire to feel a little closer to a baby who has not arrived yet.
That is really what boy or girl old wives' tales are about. They give family and friends a gentle, low-pressure way to participate in your pregnancy. They turn a doctor's appointment into a dinner-table conversation. They give grandma something to be delighted about being right (or wonderfully, charmingly wrong) about later.
We do not share any of this because we think it will tell you anything definitive about your baby. We share it because pregnancy is full of enough uncertainty and waiting, and a little bit of folklore fun makes the wait feel warmer.
The tests
Old Wives' Tales for Guessing Boy or Girl
Here is the full roundup, organized the way you will actually hear them shared: by how your body feels, how your bump looks, what you are craving, and the little rituals families have passed down for generations.
How your body feels
Several of the oldest tales are based entirely on pregnancy symptoms.
Morning sickness is one of the most talked-about signs. The tale goes that severe, all-day nausea points to a girl, while little to no morning sickness points to a boy. Interestingly, this is one of the few tales with a sliver of research behind it. Some small studies have found a loose association between elevated pregnancy hormones and more intense nausea, and elevated hormones can, in some studies, trend slightly higher with female fetuses. The evidence is far from conclusive, but it is enough to make this the tale most likely to spark a real debate.
Heartburn has its own version. Constant, fiery heartburn is said to mean your baby will be born with a full head of hair, and a girl. Little to no heartburn points to a boy. This one is almost certainly just about pregnancy hormones relaxing the muscle between your stomach and esophagus, but it makes for a fun story either way.
Your skin is said to tell a tale too. Dry, flaky skin is said to point to a boy, while oily skin and extra breakouts point to a girl, sometimes summarized as "she is stealing your beauty." Your hair supposedly follows the same pattern: shiny, thick hair points to a boy, while dry or brittle strands point to a girl.
Even your sleep and your mood get pulled into it. Trouble sleeping, vivid dreams, and extra moodiness are said to mean a girl. Calm nights and a steady mood are said to mean a boy. And the ever-popular linea nigra, that faint line that can appear down the center of your belly, gets its own reading: a line that stops at your belly button is said to mean a girl, while a line that travels all the way up to your ribs is said to mean a boy.
How you are carrying
This is possibly the most famous category, and the one strangers feel most entitled to comment on.
Carrying high or low is the headline tale: a low, out-front bump is said to mean a boy, while a high bump that spreads toward your hips is said to mean a girl. The shape gets its own reading too, often described as "basketball versus watermelon." A bump that sits round and neat like a basketball is said to point to a boy, while a wider, fuller bump is said to point to a girl.
Weight gain gets folded into the same story. Extra weight carried through your hips, thighs, and bottom is said to mean a girl, while weight that stays concentrated in your belly is said to mean a boy. None of this has a real medical basis. Where and how you carry has far more to do with your muscle tone, your body shape, and your baby's position than with your baby's sex.
What you are craving
Cravings and gender might be the most fun tale to test at a baby shower. Craving sweets, fruit, and juice is said to mean you are having a girl, while craving salty, savory foods like chips, pickles, and protein is said to mean a boy. Some versions of the tale extend this to your general mood at the table: reaching for chocolate points to a girl, reaching for the cheese board points to a boy.
There is genuinely no scientific link between cravings and biological sex. Cravings seem to be shaped by shifting hormones, nutrient needs, and honestly, whatever sounds good that day. Still, it is one of the easiest tales to poll your family and friends with.
The heart rate myth
Heart rate gender prediction old wives' tale is one of the most widely repeated claims out there, and one worth being especially skeptical of. The tale says a fetal heart rate above 140 beats per minute means a girl, while a heart rate below 140 means a boy. Doctors and midwives will tell you plainly that a normal fetal heart rate is anywhere from 110 to 160 beats per minute, and it naturally shifts based on your baby's age, activity level, and even the time of day you are measuring it. It has nothing to do with sex.
Folklore rituals and at-home tests
This is where things get genuinely fun. Families have invented dozens of little rituals to answer the question, and most of them show up at every baby shower in some form.
The ring test is probably the most famous. You dangle a wedding ring on a string over your belly. A circular motion is said to mean a girl, and a back-and-forth swing is said to mean a boy. The same idea shows up as a necklace test, a pencil test, and a needle test, all working from the same premise.
The key test hands a house key to your partner and asks them to pick it up without thinking about it. Grabbing it by the narrow end is said to mean a girl, and grabbing it by the round end is said to mean a boy.
The baking soda gender test mixes a spoonful of baking soda with a sample of your urine at home. If it fizzes, tradition says boy. If it stays flat, tradition says girl. A very similar version swaps in red cabbage water, watching for the color the mixture turns.
And then there are the ancient systems, which are less a test than a calendar you look up. The Chinese gender chart (sometimes called the Chinese gender predictor) uses your age at conception cross-referenced with the lunar month you conceived to land on a boy or girl prediction. The Mayan gender calendar works a little differently, comparing your age at conception with the year you conceived: if both numbers are even or both are odd, tradition says girl, and if one is even and one is odd, tradition says boy.
None of these have any clinical basis, but they are wonderfully fun to try, especially with family in the room, and a great excuse to plan a proper gender reveal once you are ready for the real answer.

The science
What the Research Actually Says
We want to be honest with you, because that is how we would want a friend to talk to us. Every single tale above has been studied to some degree, and the consistent finding is that old wives' tales gender prediction accuracy sits right around fifty percent. That is the same odds as a coin flip. A handful of the symptom-based tales, like morning sickness and hormone levels, have shown a very slight statistical association in small studies, but nothing close to reliable enough to bet on, and certainly nothing your doctor would use.
If you want a real answer, there are medical options. An anatomy ultrasound, typically done between eighteen and twenty-two weeks, can usually determine sex with high accuracy by checking for physical anatomy. Non-invasive prenatal testing, a blood test some providers offer as early as ten weeks, can detect fetal DNA in your bloodstream and is over ninety-nine percent accurate for sex determination, though it is primarily ordered to screen for chromosomal conditions.
But here is the thing: knowing does not have to mean knowing right away. Plenty of families we work with love spending a few extra weeks in the wondering, letting grandma have her theory about the ring test, letting cousins argue over the Chinese gender chart, before they plan a gender reveal or find out for certain at an appointment.
The fun part
How to Use These Tales Without Taking Them Too Seriously
None of this is a substitute for anything your doctor or midwife tells you. But used the right way, these tales are a genuinely lovely way to bring people into your pregnancy.
Turn it into a baby shower game. Print the list of tales, have each guest predict boy or girl based on how you are carrying, and reveal the real answer (or keep everyone guessing until the big day) over cake. Send guests home with a little something from our gender-neutral baby shower gifts collection so no one has to guess right to give a gift that fits.
Start a family prediction log. Ask everyone, grandparents, siblings, best friends, to write down their guess and their reasoning. It becomes a keepsake you can look back on once your baby arrives, and it is always funnier in hindsight than you expect.
Dress the bump (and the nursery) for either outcome. This is our favorite piece of practical advice: while you are having fun with the folklore, there is no need to guess when it comes to your baby's first wardrobe. Soft, gender-neutral basics in warm neutrals, natural creams, sage, and butter yellow mean you are ready to bring your baby home in something soft and beautiful no matter what the ring test says. Our gender-neutral baby shower gifts shop is full of bamboo viscose pieces designed to work just as beautifully for a boy or a girl.
Save the science for when you are ready. There is no wrong time to find out, whether that is at your anatomy scan, through an early blood test, or at a gender reveal surrounded by the people who have been debating the linea nigra theory with you for months.
A note from us
The Guessing Is Part of the Story
We will say this plainly: none of these old wives' tales can tell you anything real about your baby. What they can do is give you and the people who love you a reason to talk about your baby a little more, to wonder together, to feel a little closer to the tiny person you have not met yet.
That is really what this season of pregnancy is about. The waiting. The noticing. The stories families tell each other while they wait. We think that is worth celebrating, right alongside the science, the scans, and eventually, the soft little outfit you bring your baby home in.
Whichever tales turn out to be right for you, we are so glad you are here.
Common questions
Old Wives' Tales for Gender Prediction: Frequently Asked Questions
What are the most accurate old wives' tales for predicting gender?
None of the traditional old wives' tales for gender prediction are considered medically accurate, and most land right around a fifty percent success rate, the same as a coin flip. Some studies have found a very slight statistical link between severe morning sickness and elevated pregnancy hormones in people carrying girls, but the evidence is not strong enough to be considered reliable. For a medically accurate answer, an anatomy ultrasound around eighteen to twenty-two weeks or a non-invasive prenatal blood test are the only options with real clinical accuracy.
How does the old wives' tale ring test work?
The ring test involves dangling a wedding ring on a piece of string over your belly and watching how it moves. According to the tale, a circular motion means you are having a girl, while a back-and-forth swinging motion means you are having a boy. It has no scientific basis, but it is a fun, low-effort tradition to try at a baby shower or with family.
Does carrying high or low actually predict gender?
No, carrying high or low does not predict a baby's sex. The old wives' tale claims a low, out-front bump means a boy and a high bump means a girl, but how you carry is actually determined by your abdominal muscle tone, your body shape, the position of your baby, and whether this is your first pregnancy, not by biological sex.
Is the Chinese gender predictor chart accurate?
The Chinese gender predictor chart, also called the Chinese gender chart, uses your age at conception and the lunar month of conception to predict a boy or girl. It has no scientific or medical basis, and studies that have tested it against real outcomes have found its accuracy to be no better than chance. It remains a popular and fun tradition, especially for baby showers and gender reveal planning.
Does morning sickness mean I'm having a girl?
Severe morning sickness is one of the few old wives' tales with a small amount of research behind it, though it is far from proven. Some studies have found a loose association between higher pregnancy hormone levels, which can contribute to nausea, and carrying a girl, but the link is not consistent or strong enough for doctors to rely on. Plenty of people carrying boys experience severe morning sickness, and plenty of people carrying girls experience very little.
Can fetal heart rate tell you the baby's gender?
No, fetal heart rate cannot tell you your baby's sex. The old wives' tale claims a heart rate above 140 beats per minute means a girl and below 140 means a boy, but a normal fetal heart rate naturally ranges from 110 to 160 beats per minute and changes based on gestational age, activity level, and even the time of day, not sex.
What is the most reliable way to find out my baby's gender?
The most reliable ways to find out your baby's biological sex are an anatomy ultrasound, usually performed between eighteen and twenty-two weeks, and non-invasive prenatal testing, a blood test some providers offer starting around ten weeks that is over ninety-nine percent accurate for sex determination. Both are far more reliable than any old wives' tale, whether you get the news privately or turn it into a gender reveal with family and friends.
What are fun ways to guess a baby's gender at a baby shower?
Some of the most fun ways to guess your baby's gender at a shower include a printed prediction card where guests circle boy or girl based on old wives' tales, a ring test performed live in front of guests, a Chinese gender chart lookup using the mom's age and conception month, and a "sweet or salty" cravings poll based on what mom has been reaching for most. Pair the game with a few picks from our gender-neutral baby shower gifts collection so guests can gift confidently either way.
Should I buy gender-neutral clothing while I wait to find out?
Yes, gender-neutral clothing is a practical and beautiful option whether you plan to find out early, late, or not until delivery day. Soft neutral colors and prints work for either a boy or a girl, so you are never stuck waiting on a wardrobe. Many families build their whole newborn layette from our gender-neutral baby shower gifts collection, then add boy- or girl-specific pieces once they know or after the baby arrives.
