(Reuters) Growing into a fully formed human being is a long process, and scientists have found that unborn babies not only hiccup, swallow and stretch in the womb, they yawn too.
Researchers who studied 4D scans of 15 healthy foetuses also said they think yawning is a developmental process which could potentially give doctors a new way to check on a baby’s health.
While some scientists have previously suggested that foetuses yawn, others disagree and say it is nothing more than a developing baby opening and stretching its mouth.
