The Basics
Primitive reflexes are involuntary movements that develop in the womb and are present during infancy. They help your child learn to eat, reach for objects, roll over, crawl, and explore or learn their environment. Primitive reflexes are essential for survival and development in early childhood and many are often integrated by 6 months of age. Here are some examples of primitive reflexes:
- Rooting: Your baby turns toward an object when their cheek is stroked.
- Sucking: Your baby automatically sucks on a nipple or clean finger when inserted into their mouth.
- Asymmetric Tonic Neck Reflex: When your baby’s head turns to one side, the arm and leg on that side extend and the opposite arm and leg flexes.
- Tonic Labyrinthian Reflex: When your baby looks down, their arms, hips and legs want to curl in closer to the body and when they look up, their arms and legs tend to move outward.
Retained Reflexes
In some children, these primitive reflexes remain intact and are not naturally integrated. This can impact several aspects of development including:
- Motor Planning
- Muscle Tone
- Postural Control
- Balance and Coordination
- Bilateral Coordination
- Emotional Regulation
- Attention
- Vision
- Spatial Perception
In older children, retained reflexes can result in clumsiness or increased cautiousness, difficulties attending in class, challenges with remaining seated, feeling fidgety, feeling anxious, or having emotional regulation challenges.
What Can I Do at Home?
Engaging your child in a variety of activities and exercises can help integrate retained reflexes. Activities that require crossing the body midline, using both hands together, and crawling scavenger hunts that promote independent head movements are some examples. However, if you suspect that your child may have retained primitive reflexes, consult your occupational therapist. They can best determine which, if any, reflexes your child has retained and provide an individualized treatment program for them.
