We all have reflexes. They are a type of involuntary movement or action that occurs in response to a stimulus. When you go to the doctor and they hit your knee with a light hammer, your leg automatically kicks outward in response. That’s a reflex. Certain reflexes are unique to newborns, depending on their stage of development. But a lack of
certain reflexes can sometimes signal problems with the baby's brain or nervous system. Root reflex. This newborn reflex is triggered by touching the corner of the baby’s mouth. Your baby will turn their head in the direction of the touching. With their mouth open, they’ll “root” in that direction. This rooting aids in feeding, as it helps the baby find the bottle or breast that will
nourish them. This reflex lasts about 4 months. Sucking reflex. The rooting reflex sets the stage for the sucking reflex, which allows the baby to breastfeed safely. When the nipple touches the roof of the baby’s mouth, they automatically begin to suck. The sucking reflex helps coordinate the rhythms of sucking, breathing, and swallowing. This reflex gets stronger the more the baby does it and will evolve into habits like
sucking their thumb for comfort. The sucking reflex develops before the baby is born. It begins around week 32 of pregnancy and fully develops around week 36. Moro reflex. The Moro reflex, also called the startle reflex, is the baby’s reaction to being
startled. The cause is often a loud sound, a sudden movement, or even their own cry. As an adult, you may jump and blink when something startling happens. When the Moro reflex is triggered, the baby throws their head back, throws out their arms and legs, cries, and quickly pulls their limbs back in. This reflex lasts for only the first 2 months. Tonic neck reflex. The tonic neck reflex is sometimes called the fencing position because the baby holds their arms in a
position like they’re fencing. The tonic neck reflex happens when the baby turns their head to one side with their arms stretched out. If their head is turned to the right, the right arm will stretch out while the left arm bends up at the elbow. This reflex might be difficult to notice. The movements can often be subtle. Your baby may not do it at all if they are fidgeting or crying. This reflex lasts until 5
to 7 months of age. Grasp reflex. You’ve probably noticed this reflex when you put your finger into your baby’s hand and they grasp it. The grasp reflex happens when you lightly touch the palm of their hand. The sensation causes the baby to close their fingers. This reflex lasts until around 6 months of age. Babinski reflex.
This reflex is similar to the grasp reflex. When you stroke the bottom of your baby’s foot, the big toe will bend back while the other toes fan out and away. This reflex disappears between 12 months and 2 years of age. Stepping reflex. You probably get a bit surprised when you hold your baby upright on the floor and they try to walk. This is simply the stepping
reflex at work. It is also called the walking or dancing reflex. You'll want to be wary of this reflex, as your newborn still cannot support their own weight. Helping them stand upright by holding underneath their arms will trigger the stepping reflex. They’ll start to step forward as if walking. The reflex will disappear after the first 2 months and reappear after the first year, when the baby
begins learning how to walk. Because the tonic neck, grasp, Moro, Babinski, and stepping reflexes use each half of the body, it’s important to know that they’re symmetrical. If the reflexes are not equally strong or quick on both sides of the body, there may be a problem with the baby’s central nervous
system. Talk with your doctor if you notice a lack of symmetry in your baby's reflexes. Newborn reflexes, also known as baby reflexes or infant reflexes, are normal and are crucial for a baby’s survival. They are the baby’s muscle reactions, involuntary movements or neurological responses to stimulation or triggers which may include sound, light, sudden movement and being stroked or touched. Doctors and nurses check baby reflexes to determine if a baby’s brain and nervous system are functioning properly. If you notice abnormal reflexes in your child, please see a doctor as these may indicate a dysfunction in the central nervous system. There are many different types of newborn reflexes. You will notice many of them as you interact with your baby, and they can be really cute and fun to watch. Some reflexes only occur in specific periods of the baby’s development, but some can stay for years, all the way through adulthood. It’s good to note though that some adults who have brain damage or who have experienced stroke may experience baby reflexes as well. Moro ReflexBabies usually exhibit a full Moro reflex which includes the arms, head and legs in their first 12 weeks after birth. Also called the startle reflex, Moro reflex usually occurs when a baby gets startled by a loud sound, sudden movement or intense light. As a response to the trigger, the baby suddenly lifts the arms and legs, curl them back toward the body and then throw the head back. Your baby's own cry may also startle him/her and trigger the Moro reflex. Some babies experience an abnormal Moro reflex which only involves one side of the body. Other babies may have no Moro reflex at all. Some causes of an abnormal or absent Moro reflex may include infections, muscle weakness, injuries from childbirth, peripheral nerve damage and spastic cerebral palsy. When Does the Startle Reflex Go Away?The Moro or startle reflex usually lasts until the baby is about five to six months old. Rooting ReflexThis newborn reflex begins by touching or stroking the corner of the baby's mouth or when it touches the mother’s skin or nipple. When triggered, you will notice that the baby will turn his/her head and open his/her mouth to follow and "root" in the direction of the stroking. The rooting reflex helps the baby find the breast or bottle and also helps prepare him/her to suck. When Does the Rooting Reflex Go Away?The rooting reflex in babies usually lasts for about four months. After that, rooting becomes a voluntary response rather than a reflex. Sucking ReflexThis type of reflex usually starts when the baby is about 32 weeks inside the mother’s womb. If you’re pregnant, you may see your baby sucking his/her thumbs or hands during an ultrasound. When the baby is born, the sucking reflex happens in two stages. First, when the roof of the mouth is stimulated or when you place the mother’s breast or a bottle in his/her mouth, the baby will place the lips over the nipple and squeeze it between the tongue and roof of the mouth. Next, the baby will move his/her tongue to the nipple to suck and milk the breast. Premature babies may take weeks to properly suck and swallow which is why some doctors recommend a feeding tube inserted through the nose into the stomach to help them get the nutrients they need. When Does the Sucking Reflex Go Away?The sucking reflex usually lasts until the baby is four months old. Tonic Neck ReflexAlso known as a fencing reflex, the tonic neck reflex happens when the baby's head turns to one side. This is triggered when you stroke or tap the side of the baby’s spine while the baby lies on his/her stomach. For instance, if the baby’s head turns to the right, the right arm will stretch out and then the left arm will bend at the elbow, forming a so-called "fencing" position. When Does the Tonic Neck Reflex Go Away?Tonic neck reflex may last until the baby is around five to six months old. Grasp ReflexStroking or touching the palm of a baby may cause the baby to automatically close his/her hands. For example, when you place your finger on the baby’s palm, he/she will grasp it and hold onto your hand because of the grasp reflex. When Does the Grasp Reflex Go Away?The grasp reflex may last until the baby is about five to six months old. Babinski ReflexThe Babinski reflex happens when you firmly stoke the sole of the baby’s foot. The baby’s big toe moves upward or toward the top of the foot and the other toe fans out. When Does the Babinski Reflex Go Away?The Babinski reflex usually lasts until the child is about two years old, but for some, it goes away after a year. Stepping ReflexThis cute reflex is also called the walking or dancing reflex. Stepping reflex happens when you hold the baby upright with his/her feet touching a flat surface. You will notice that the baby will move his/her legs as if he/she is walking or trying to take steps although the baby is still too young to actually walk. When Does the Stepping Reflex Go Away?The stepping reflex often lasts for about two months. Please see a pediatrician in Detroit if you have worries about your baby’s development or if he/she continues to experience newborn reflexes beyond the normal period as this may be a sign of a nervous system dysfunction. One of our pediatricians in Detroit may perform exams that can help determine if your baby experiences abnormal infant reflexes as well. If your baby was born prematurely, don’t compare his or her development to that of full-term newborns. Premature babies are usually behind full-term babies in terms of development. Which reflex is a response to a touch on the palm of the hand?Grasp reflex
