Can old wives’ tales predict a baby’s gender?
Old wives’ tales gender prediction is a collection of folklore guesses, not a reliable way to establish a baby’s sex. Stories about cravings, bump shape, heartbeat and a swinging ring can be a lighthearted conversation starter. A matching guess does not make a story a dependable test.
Explore eight familiar tales, read what research says about them and download a printable guessing game. The familiar phrase “gender prediction” refers here to boy/girl guesses about sex; these activities do not predict a child’s future gender identity.

Eight common pregnancy tales, with their limits
Families often tell different versions of these stories. Here are the familiar ideas and the evidence behind them. Use them for conversation, not to interpret symptoms or replace prenatal care.
| Tale | Common idea | Evidence and limits |
|---|---|---|
| Food cravings | Sweet or salty preferences are treated as clues. | The NHS describes pregnancy cravings in relation to hormone-related changes in taste and smell. That explanation is not a boy/girl prediction rule. NHS guide to week 5. |
| Bump shape | Carrying high or low, or looking round or pointed, is assigned a guess. | A 1999 questionnaire study of 104 pregnant women found no systematic relationship between abdominal shape and fetal sex. The study was small and did not assess every possible body measurement. Perry and colleagues, 1999. |
| Heart rate | A faster or slower fetal heartbeat is said to indicate a boy or girl. | A study of 655 pregnancies found no significant difference between male and female fetal heart rates at 8-13 weeks. It does not support the usual first-trimester heartbeat guess. Bracero and colleagues, 2016. |
| Morning sickness | The amount of nausea is read as a clue. | Some studies find average differences between pregnancies with boys and girls. This does not make nausea a reliable home test for one pregnancy. See the explanation below and Young and colleagues, 2021. |
| Skin changes | Pregnancy glow or acne is used to make a guess. | Cleveland Clinic explains that hormones and increased blood flow can affect skin during pregnancy. Its obstetrician’s explanation does not endorse glow or acne as a sex predictor. Cleveland Clinic, 2023. |
| Hair changes | Thicker or different-looking hair is treated as a sign. | Hormone-related hair changes are described in the same Cleveland Clinic guide. A change in appearance is not an established prediction method. Read the explanation of hair changes. |
| Ring swing | A ring on a string moves in a circle or a line, and a guess is assigned to the direction. | A 2021 motion-capture experiment showed how small finger movements can drive a hand-held pendulum. This was a movement study, not a fetal-sex study; it does not validate a ring prediction. Cantergi and colleagues, 2021. |
| Chinese calendar | A traditional chart combines lunar age and lunar conception month. | A 2010 study of 2,840,755 singleton births found no predictive agreement beyond chance for the calendar method. Villamor and colleagues, 2010. Our calendar accuracy guide also discusses a 2023 study. |
Does more morning sickness mean a girl?
A survey of 4,320 pregnancies found somewhat more first-trimester nausea and vomiting on average with female fetuses. That does not mean nausea can tell you an individual baby’s sex. The 2021 paper, published online in 2020, asked people to recall their experiences rather than measuring symptoms as they happened. Read the original study abstract.
An average difference between groups does not give an answer for one person. Having nausea, or having none, does not establish that someone is carrying a girl or boy. Questions about symptoms belong with the person’s maternity care team.
What if all your guesses agree?
Even if every tale points to the same answer, it is still a collection of guesses. A dependable test needs research showing how often it is right and wrong. Matching stories alone cannot tell you a baby’s sex.
The Chinese gender predictor is another traditional guess. It matches the mother’s lunar age with the lunar month of conception, but research has not found it more reliable than chance. Read how to use the Chinese gender calendar if you want to try it.
Keep the party sheet as a memento. If the parents later share an announcement, comparing the guesses can be part of the fun, but a few matching answers do not prove the tales work.
How to play the printable guessing game
Players: any number, one sheet per guest or small group. Time: about 5 minutes. Materials: printed sheets and pens. No physical tests or medical information are needed.
- Let the parents set the boundaries. Decide whether this is a pre-announcement game or simply a conversation activity. Skip any subject they do not want discussed.
- Make optional observations. Use only a detail the parents have already chosen to share, or leave that column blank. Do not ask guests to inspect someone’s body or report health information.
- Write a guess. Each row can say Boy, Girl or Surprise. Skip any row you like; there is no score to reach.
- Collect the sheets. If the parents share an announcement, guests can compare their guesses. An overall tally is only a tally of guesses; there is no need to name a winner.
For the ring row, you can write a guess without using a ring. If a host uses a pendulum as a party prop, keep it above a clear table, away from anyone’s body. Do not suspend objects over a pregnant person or baby. For a game without pregnancy observations, try the printable Bingo, word scramble and other party games.
Questions about old wives’ tales
Which old wives’ tale is the most accurate?
None of these tales has been established as a dependable prediction for an individual pregnancy. A correct guess last time does not make it reliable the next time.
Can the ring test tell me my baby’s gender?
Treat the ring swing as a folklore game. The 2021 pendulum experiment explains movement generated by the person holding the string; it did not test pregnancies or establish a ring’s ability to determine fetal sex. Circle-versus-line rules are game conventions, not test results.
Can I use these guesses for a gender reveal announcement?
Keep them as activities before or after the announcement. The announcement should use only information the parents have chosen to share, not a result from folklore or this website. The NHS explains that fetal sex may sometimes be visible during a mid-pregnancy scan, depending on hospital policy and the baby’s position, and that the sonographer cannot be 100% certain. Read the NHS ultrasound guidance.
Can I play without sharing pregnancy details?
Yes. Leave the observation spaces blank, write a few playful guesses or choose Surprise. No pregnancy details are needed, and anything you write on a printed sheet stays on that sheet.
