How to Perform an Infant Exam: Checking Reflexes for Optimal Development

When it comes to your baby’s development, checking reflexes is a simple but important step to ensure their nervous system and motor skills are developing properly. These reflexes are essential for survival in the early months, but they also give us valuable insight into how your baby is progressing. Let’s break down how to check some of the key reflexes and developmental markers, so you can better understand your baby’s growth.

What Are Primitive Reflexes?

Primitive reflexes are automatic movements triggered by specific stimuli in infants. These reflexes play a huge role in early development, and they’re meant to fade as the nervous system matures. Tracking these reflexes and their timing can help us determine if your baby is on the right developmental path or if further attention is needed.

Essential Reflexes to Check in Infants

1. Rooting Reflex

What to Do: Gently stroke the side of your baby’s face.
What to Look For: Your baby should turn their head toward the stimulus, open their mouth, and start sucking.
Why It’s Important: This reflex is critical for developing feeding behaviors, which will later support speech development. It typically fades around 3-4 months of age.

2. Palmar Grasp Reflex

3. Babinski Reflex

What to Do: Stroke the outside of your baby’s foot, from the heel to the toes.
What to Look For: Your baby’s toes should fan out, and the big toe might extend upward.
Why It’s Important: This reflex helps us understand how your baby’s central nervous system is functioning, and it usually lasts until around 12 months.

4. Spinal Galant Reflex

What to Do: Lay your baby on their stomach or hold them upright. Stroke one side of their lower back.
What to Look For: Your baby should curve their body toward the side that’s being stimulated.
Why It’s Important: This reflex helps motor development and can highlight any issues with the spinal or nervous system.

5. Moro (Startle) Reflex

What to Do:Move your baby quickly or let their head drop slightly while supporting their neck.
What to Look For: Your baby’s arms should splay out, and then pull back toward their body.
Why It’s Important: This reflex is key for nervous and vagal system development. It usually fades by 3-4 months. If it doesn’t, it could indicate challenges with anxiety or attention regulation later on.

6. Asymmetrical Tonic Neck Reflex (ATNR)

Range of Motion and Chiropractic Insights

Along with reflexes, it’s essential to assess the range of motion, particularly in your baby’s neck. Smooth, unrestricted head movement is key to proper reflex development and motor milestones.

If you notice limited movement, it’s a good idea to consult with a pediatric chiropractor or healthcare provider. Don’t try to force any movement, as it could cause harm.

Why Early Detection Matters

Primitive reflexes lay the groundwork for later motor and cognitive development. If any of these reflexes are absent, delayed, or last longer than expected, it could indicate developmental delays or neurological concerns. The good news is that early intervention can make a significant difference in helping your baby thrive.

Checking your baby’s reflexes is a simple, yet powerful way to track their development. By paying attention to these reflexes and ensuring your baby’s range of motion is full, you’re supporting the development of a healthy nervous system and motor function. If you ever have any concerns or questions, don’t hesitate to reach out to a professional who can offer guidance.

Taking these simple steps now can have a lasting impact on your baby’s healthy growth and development!
