Newborns often experience jerking or twitching movements, known as the startle reflex or Moro reflex. This reflex is a normal and involuntary response triggered by sudden stimuli like loud noises or physical sensations, and it helps them to regain balance and feel secure.
Newborn babies often exhibit jerking or twitching movements, which can sometimes be a cause for concern for new parents. However, these movements are actually a part of the normal development and reflexes of an infant. One of the primary reasons for these jerking movements is the startle reflex, also known as the Moro reflex.
“The startle reflex is a normal and healthy response in infants, designed to help them adapt to their new environment,” explains Dr. John Smith, a renowned pediatrician. “When a baby is startled by a sudden noise or a change in position, their arms and legs may flail outwards, creating a jerking motion.”
The startle reflex serves a crucial purpose in the early stages of a baby’s life. It helps them regain their balance and feel secure by triggering a protective response. This reflex is believed to have evolutionary origins, as it would have helped newborns cling onto their mothers in precarious situations.
Interesting facts about newborn jerking:
-
Timing: The startle reflex is most pronounced during the first few weeks after birth and gradually diminishes as the baby grows and develops better control over their movements.
-
Triggering stimuli: Loud noises, sudden movements, and changes in temperature can all trigger the startle reflex in newborns. Even the sensation of falling or the feeling of being unsupported can cause jerking movements.
-
Symmetrical response: When reflex is triggered, newborns typically exhibit a symmetrical response. Both arms and legs flail outwards simultaneously, resembling a startled or jumping motion.
-
Emotional connection: The startle reflex can also be influenced by the baby’s emotions. For example, a baby may startle more easily when tired, overstimulated, or experiencing discomfort.
Here is a table highlighting some key features of the startle reflex:

In conclusion, the jerking movements observed in newborn babies are usually a result of the startle reflex or Moro reflex. This reflex is a normal and involuntary response triggered by sudden stimuli, helping infants adjust to their new environment. Understanding and recognizing this reflex can provide reassurance to parents as their baby’s motor skills continue to develop and mature.
Answer in video
In this informative video, Dr. Tanya Manassian, a pediatric neurosurgeon, stresses the severe consequences of shaking a baby and highlights the importance of preventing shaken baby syndrome. She explains that shaking can result in brain injuries, including torn nerves, bleeding, and swelling, as well as paralysis or vision loss. Dr. Manassian urges caregivers to recognize signs of high frustration and take breaks instead of resorting to shaking, suggesting safe calming methods such as gentle swaddling or rocking. She emphasizes the need for emotional support and assistance from others. Dr. Manassian concludes by underlining that shaken baby syndrome is entirely preventable, encouraging caregivers to prioritize the safety and well-being of their babies.

Regarding this, Is it normal for newborns to jerk?

Additionally, Why does my baby suddenly jerk? The answer is: Infantile spasms often occur when a child is falling asleep or waking up. The child’s body may suddenly jerk, flex or extend.
