20 Myths About Predicting a Baby's Sex

Sleep Position

Pay attention to your sleep position at night. If you prefer sleeping on your left side, you're supposedly having a boy. Right side? This old wive's tale says you're pregnant with a girl.

Upset Stomach

Although it's not clear why, some research might support the myth that if you experience extreme morning sickness, you're having a girl.

For example, in a 2021 study of 4,320 pregnancies, those carrying a female fetus reported a significantly higher frequency of nausea during the first trimester than those who were pregnant with males.

Soft or Dry Hands

As the old wives' tale goes, you might have a boy if your hands are dry during pregnancy. But, on the other hand, soft hands are mythically linked with girls.

Food Cravings

According to lore, your favorite pregnancy food cravings may indicate if you're pregnant with a boy or a girl. Supposedly, if your pregnancy cravings involve potato chips, pretzels, popcorn, or other salty foods, you're more likely to be pregnant with a boy.

If you are more likely to have a desire for ice cream, chocolate, and candy, however, those sweet cravings are associated with having a girl. Citrus cravings have also been associated with girls. However, it's important to note that food cravings often cover a wide range, with sweets, high-fat foods, and fast food being among the most common.

Acne

Are pregnancy hormones making your skin break out? If so, the old wives' tale says you might be expecting a girl. However, the reality is that many people have acne during pregnancy due to changing hormone levels, no matter their baby's sex.

Graceful or Clumsy Pregnancy

If you feel as though you're gliding through the day, rumor has it you're having a girl. Stumbling around? It just might be a boy says this myth.

Face Weight Gain

If your face gets fuller during pregnancy, a girl might be on the way. That said, everyone experiences weight distribution differently, so it may have more to do with your body than your baby's sex.

Also, if you experience extreme sudden puffiness in your face, talk to a health care provider, since this can be a symptom of preeclampsia.

Mood Changes

Mood swings are common during pregnancy. Legend has it that if you're constantly switching between happiness and sadness and anger—and every other mood in between—you might expect a baby girl to join your family. However, like other items on this list, it's best not to read into this one too much. Mood swings affect lots of pregnant people, and are typically caused by changes in hormones, fatigue, or physical stress. But if you find that your mood swings are frequent, intense, or reflect symptoms of depression, consult a health care provider for further assistance.

High or Low Pregnant Belly

As it turns out, old wives' tales for pregnancy bellies also exist. They say if you're carrying the baby low on your stomach, a baby boy might be in your future. If it's high, you're supposedly having a girl.

Pendulum Test

This myth about gender prediction might seem strange, but it's all in good fun. Dangle a chain with a pendulum (or charm or ring) over your belly. If it swings back and forth, the myth says you've got a boy; if it swings in a circle, you might have a girl.

Hand Display

"Show me your hands." Hold out your hand as your normally would in response to this question. A palms-up position means you're having a girl, while hands-down could indicate a boy.

How You Carry Your Weight

Tune into how you carry your pregnancy weight. Those who carry their baby in front might expect a boy, while weight spaced more evenly around your middle could indicate a girl.

Oddly, science has found a connection between gestational weight gain and fetal sex. For example, a 2014 study published in PLOS One analyzed 68 million births over 23 years and found that those who gained more weight were statistically more likely to give birth to a boy.

Toddler Advice

You'll need a little boy for this one, whether it's your own son, a nephew, or a friend's child. The old wives' tale says if the boy is interested in your belly, it's a girl; if he ignores your belly, it's a boy.

Eating Garlic

Some say you can guess your baby's sex by eating garlic—who knew? If the smell seeps out of your pores, rumor says you're having a boy. If there's no scent, it's a girl.

Holding a Key

Grab the nearest house key or car key. Did you pick it up by the round end? The old wives' tales say you're expecting a boy. But, on the other hand, picking it by the long end means you might give birth to a girl.

Even and Odd Numbers

As the old tale goes, if your age and year of conception are both even numbers—or both odd numbers—a girl is on the way. One even and one odd number indicates a boy.

Baby's Heartbeat

Listen to your little one's heartbeat. You're supposedly pregnant with a girl if you detect more than 150 beats per minute. Hearing less than 150 beats per minute points to a boy.

Stress Test

According to old wives' tales for gender prediction, a child tends to be the same sex as the parent who is less stressed at the time of conception. (Of course, this tale presumes a heteronormative baby-making experience and doesn't account for fertility assistance or same-sex parents.)

Pregnancy Dreams

This old wives' tale might be a little surprising! If you dream about having a girl while pregnant, you might wind up having a boy—and vice versa.

Breast Size

Take a good look at your pregnancy breasts. If your right breast is larger than the left one, it could mean you're growing a girl. If the left breast is larger, it could be a baby boy.
