The STNR Reflex – A Simple Guide for Parents and How to Support It at Home

As a pediatric occupational therapy practitioner, I often meet parents who are doing everything they can to help their child succeed—but still notice things like poor posture, trouble focusing, or difficulty with coordination.

What many families don’t realize is that these challenges can sometimes be connected to something called a primitive reflex—specifically, the Symmetrical Tonic Neck Reflex (STNR).

The good news? With the right support and simple activities at home, you can help your child build stronger movement patterns in a fun, natural way.

 

What Is the STNR Reflex?

The STNR reflex plays an important role in your baby’s early development.

It usually appears between 6–9 months of age and helps babies learn to move from lying on their tummy into a crawling position.

Here’s what it looks like in action:

• When a baby looks up, their arms straighten and legs bend
• When a baby looks down, their arms bend and legs straighten

This movement pattern helps babies get onto their hands and knees—an important step toward crawling.

By around 9–11 months, the reflex should naturally integrate (fade away) as your child gains more controlled, voluntary movement.

 

What Happens If the Reflex Doesn’t Integrate?

Sometimes the STNR reflex sticks around longer than expected. When that happens, it can affect how a child moves, sits, and even focuses.

Parents might notice things like:

• During School or Table Activities
• Slouching or constantly shifting positions (I often see kids subconsciously wrap their legs around chair legs to “fight” the reflex)
• Resting their head on the desk
• Trouble sitting still
• Difficulty copying from the board

Movement & Coordination

• Awkward or stiff movements
• Trouble with sports or coordination
• Difficulty using arms and legs independently

Learning & Attention

• Fatigue during schoolwork
• Poor posture impacting focus
• Challenges with visual tracking (important for reading)

It’s important to remember—these signs don’t mean something is “wrong.” They simply suggest your child’s body may still be working through early movement patterns.

 

Why Does Reflex Integration Matter?

Primitive reflexes are meant to help early development—but once they’ve done their job, the brain needs to move on to more advanced control.

When a reflex is still active:

• The body may rely on automatic (involuntary) movements
• Posture and stability can be less efficient
• Focus and coordination can be harder to maintain

As reflexes integrate, children often show improvements in:

• Core strength and posture
• Coordination
• Attention and learning readiness

 

Simple, Play-Based Ways to Support Your Child at Home

The best part? Supporting STNR integration doesn’t require anything fancy.

Movement and play are the most powerful tools!

Here are some easy, effective ideas you can try at home:

Cat/Cow Stretch (Make It a Game!)

Have your child get on their hands and knees.

• Look up → arch the back (“cow”)
• Look down → round the back (“cat”)

This mirrors the STNR pattern and helps the brain learn to control it.

Try 8–10 slow repetitions and turn it into a fun animal game!

 

Animal Walk Adventures

These help strengthen the core and promote coordinated movement, helping the brain separate the upper and lower body.

Inch Worm

Crab walks

Bear Walks

You can:

• Race across the room
• Pretend to be animals in the jungle
• Add obstacles for extra fun

 

Crawling & Obstacle Courses

Crawling is one of the BEST activities for integrating this reflex.

Create a simple obstacle course using:

• Pillows
• Blankets
• Chairs or tunnels

Encourage your child to crawl through, under, and around.

 

Wheelbarrow Walking

Hold your child’s legs while they “walk” on their hands.

- Builds upper body strength
- Encourages body awareness and control

Start with short distances and build up over time.

Play on Vertical Surfaces

Try activities like:

• Coloring on a chalkboard
• Drawing on paper taped to the wall
• Using an easel

This helps improve posture and reduces slouching during seated tasks.

 

You don’t need hours of structured exercises each day.
Just a few minutes of intentional, playful movement can make a big difference.

Consistency matters more than perfection!

 

When Should You Seek Extra Support?

If your child is having ongoing challenges with:

• Sitting still
• Coordination
• School tasks
• Posture or fatigue

An Occupational Therapist can provide:

• A detailed assessment
• Personalized strategies
• Support tailored to your child’s needs
