There are several reflexes that newborns are born with, which help them survive. These reflexes are involuntary movements or actions that occur in response to a stimulus. The following list includes 7 common newborn reflexes with their average appearance and disappearance timelines, based on information from HealthyChildren.org:
| Reflex | Age When Reflex Appears | Age When Reflex Disappears |
|---|---|---|
| Rooting | Birth | 4 months |
| Palmar Grasp | Birth | 5–6 months |
| Moro Reflex | Birth | 2 months |
| Tonic Neck Reflex | Birth | 5–7 months |
It is important to note that while the linked resource outlines four reflexes, other sources identify more than four. The following are additional common newborn reflexes:
- Stepping Reflex: When held upright with feet touching a surface, babies will move their legs in a walking motion.
- Sucking Reflex: When an object is placed in a baby's mouth, they will automatically start to suck. This is essential for feeding.
- Babinski Reflex: When the sole of a baby's foot is stroked, the big toe will extend upward and the other toes will fan out. This reflex disappears as the baby matures.
These reflexes are crucial indicators of a newborn's neurological development. Here's a more detailed look at the first four, based on the provided reference:
- Rooting Reflex: When you gently stroke a newborn's cheek, they will turn their head towards the touch and open their mouth, looking for the nipple. This helps them find food.
- Palmar Grasp Reflex: When you place your finger in a baby’s palm, they will automatically grasp it tightly. It’s a strong, involuntary hold.
- Moro Reflex: Also called the startle reflex, this occurs when a baby feels like they are falling or are startled by a loud noise. They will throw back their head, extend their arms and legs, and then quickly bring their arms back towards their body.
- Tonic Neck Reflex: When a baby’s head is turned to one side, the arm and leg on that side will extend while the arm and leg on the other side will flex or bend. It looks like a fencing posture.
These reflexes are temporary and typically disappear as the baby's nervous system matures. The specific timing of these disappearances can vary slightly from baby to baby, but they generally follow the age ranges listed above. The presence and strength of these reflexes are checked during routine newborn assessments by healthcare professionals. The absence or prolonged presence of these reflexes can indicate a potential developmental issue and may need further evaluation.
