Throughout the second and 3rd trimester, fetuses yawn frequently, and those yawns can be differentiated in four-dimensional ultrasounds from various other mouth-opening %%PRO7%%s. As the fetuses develop, they seem to yawn less frequently, the analysts added. The searchings for, released Nov. 21 in the journal PLoS One, suggest yawning patterns of the fetus around pregnancy can be made use of to analyze whether an expanding fetus is developing typically. Experts don't know why grownups, let alone babies, yawn, said study co-author Nadja Reissland, a developmental psychologist at Durham University in the United Kingdom. However yawning behavior modifications throughout life. [ See Images of Yawning in the Womb ]
Yawns in grownups are transmittable, however babies don't catch them. Anemic babies yawn more in utero than healthy ones, according to a 1999 study detailed in the journal Ultrasound Obstetrics and Gynecology.

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
