Moro reflex or Startle reflex is used to describe the quick movement of newborns, infants, and babies up to the age of 4 to 5 months. You’ll notice it when it happens because it’s like your baby spontaneous receives a jolt of energy and their natural response is a quick reflex movement of their body. You don’t need to worry, as this is a common occurrence for babies.
Doctors who studied and identified moro reflex believes it’s part of the natural development of babies. Moro reflexes causes the arms to extend and potential grab hold of their mother as a form of security blanket.
The negative impact of moro reflexes is that the quick movement can wake up a sleeping baby. By using a swaddle blanket, the comfort and warmth of the wrap around a newborn can help reduce the startling a baby and potentially help your newborn sleep for a longer time.
