While some researchers have suggested that fetuses yawn, others have disagreed and claim it is simple mouth opening.
But the new research clearly distinguished 'yawning' from 'non-yawn mouth opening' based on the duration of mouth opening. The researchers did this by using the 4D video footage to closely examine all events where a mouth stretch occurred in the fetus.
Using their newly developed criteria, the research team found that over half of the mouth openings observed in the study were classed as yawns.
The study was carried out on eight female and seven male fetuses from 24 to 36 weeks gestation. The researchers found that yawning declined from 28 weeks and that there was no significant difference between boys and girls in yawning frequency.
Although the function and importance of yawning is still unknown, the study findings suggest that yawning could be linked to fetal development, and as such could provide a further medical indication of the health of the unborn baby.

Yo, slacker fetus!
Gotta get yourself some of that 5 Month Energy crap...

And these reactions have been observable for months.
Yawning? Maybe she's bored. Time for a jiggity jig!

When I was pregnant with my first, he use to click his mouth. The sound was like putting your finger in your mouth and popping it out. Even my husband heard it when he did it. We couldn’t figure it out.
Then when he was born, he made the same clicking noise. It was amazing!
Nine months in the dark, with no TV, no Internet, no Facebook, no Twitter. Who wouldn’t be bored?
LOL
