Footage records the bizarre moment that an unborn child wriggles vigorously inside its mother's womb, sending multiple visible ripples over her tummy.
The remarkable clip was recorded by a heavily pregnant woman with a very swollen tummy. It shows her unborn child moving, kicking, and rolling over inside her. The baby pushes against the wall of its mother's womb as if it can't wait to be born.
According to Daily Mail, the mother-to-be began recording when she noticed that her baby was moving inside her with unusual vigor.
Some online viewers said jokingly that the unborn child appears to be dancing inside its mother.
In the scene, an alien incubating inside a movie character exits its host by ripping and bursting out through his chest.
But despite the bizarre comparison to the popular science fiction horror movie, it is not unusual for pregnant women to feel their unborn babies moving in the womb after 16 weeks. The movements do not hurt the mother although it could be vigorous, as shown in the video.
Fetuses experience a degree of weightlessness similar to the experience of astronauts in space because they are suspended in their mother's intrauterine amniotic fluid. And like astronauts floating in space, they feel a need to exercise their muscles, thus the movements the mother begins to feel after about 16 weeks of pregnancy.
The mother feels the first movements of her baby as faint butterfly flutters. The movements are so subtle that they could be difficult to distinguish from normal bowel movements or even the fluttering motions of the mother's cardiac activity.
Mothers-to-be are more likely to feel the movements when they are still and quiet, such as when sitting or lying down. And when the movements are noticed, they are a reassuring sign that the baby is developing normally.
As the baby grows bigger and stronger and takes up more space in its mother's womb, the movements are stronger and may be felt as elbow jabs and kicks. They also come more frequently.
Generally, pregnant women are advised to see their doctor if they do not feel their baby's movement after 25 weeks. The doctor or the midwife will listen for the baby's heartbeat, conduct a scan and carry out other necessary checks.
However, experience has shown that many first-timers are less sensitive to their fetus's movements.
Experts say that babies tend to be most active at the most inconvenient time for the mother -- between 9 p.m. and 1 a.m., just the time that the mother is trying to get some sleep. This is because the baby has its daily cycle of wakefulness and sleep.
The baby tends to be most active between 9 p.m. and 1 a.m., due to daily fluctuation in its blood sugar level.
