Medical practices are expanding with every day, the latest found fact is that unborn babies actually yawn in womb.

Yes, scientists have recently added to their list of activities performed by the unborn babies in the womb that they yawn along with taking hiccup, doing swallowing and stretching in the womb.

Above claims were made after a team of researchers studied 4D scans of 15 healthy fetuses and revealed that yawning acts as a developmental process for the fetus. With this discovery, researchers are suggesting a newer way with which they believe doctors can check upon a baby's health thoroughly.

It was initially also suggested by few scientists that fetuses yawn but not all the professionals agreed to the findings explaining that a developing baby usually opens and stretches its mouth, which could appear as if the baby yawned.

Now, the writings in the journal PLOS ONE of Wednesday have all cleared the fact found by the British researchers, which say that the baby in the womb yawn along with the findings of their study that clearly distinguish baby's yawning from "non-yawn mouth opening".

Credit of the above findings goes to the 4D video footage technology that was used by the professionals to examine all the times when fetuses opened their mouths.
