Reflexes in Newborns: What’s Normal?

Quick Answer

Newborn reflexes are automatic, involuntary movements that indicate normal neurological development. These reflexes—such as the Moro (startle), rooting, sucking, and grasp reflex—are present at birth and gradually integrate (fade) as the baby’s brain matures. Pediatric providers use these reflexes as part of early neurological assessment. Variations can occur, but absent, asymmetrical, or persistent reflexes should be evaluated by a healthcare provider.

Key Takeaways

• Newborn reflexes are involuntary responses controlled by the nervous system.
• They are present at birth and change over time as the brain matures.
• Common reflexes include Moro, rooting, sucking, and grasp.
• Reflexes support survival, feeding, and early development.
• Most reflexes integrate within the first few months of life.
• Symmetry matters—both sides of the body should respond similarly.
• Reflexes are used in newborn neurological assessments.
• Variations may be normal, but persistent or absent reflexes should be evaluated.
• Reflexes are not behaviors the baby can control.
• Understanding reflexes helps reduce unnecessary concern.

Introduction

Newborns enter the world with a set of built-in responses.

These are not learned behaviors.

They are reflexes—automatic movements that occur without conscious control.

For new parents, these movements can sometimes feel surprising.

A sudden startle. A tight grasp. A head turning quickly toward touch.

Without context, these responses can seem unusual or even concerning.

In reality, they are expected and important.

Newborn reflexes provide insight into how the nervous system is functioning and developing in the earliest weeks of life.

What Are Newborn Reflexes?

Newborn reflexes are controlled by the brainstem and are part of early neurological function.
According to the

National Library of Medicine
, these reflexes are present at birth and are gradually replaced by voluntary movements as the brain develops.

• Survival
• Feeding
• Protection
• Early movement patterns
