Every baby is born with a set of automatic movement patterns called primitive reflexes - the Moro (startle), the STNR, the spinal Galant, and others. They exist to help a newborn survive and develop, and in most kids they fade into the background by early childhood as the brain matures. When one does not fully integrate, it can keep firing in the background for years, showing up as things that get labeled as clumsiness, bad handwriting, poor balance, or big emotional reactions that seem to come out of nowhere.
Common signs of retained reflexes
- Persistent toe-walking
- Frequent tripping or poor balance
- Messy handwriting or trouble sitting still at a desk (often linked to a retained STNR)
- Exaggerated startle response to noise or touch (often linked to a retained Moro reflex)
- Bedwetting past the expected age (sometimes linked to the spinal Galant reflex)
None of these signs mean something is definitely wrong - plenty of kids show one or two without a retained reflex being the cause. But when several show up together, or a child is not responding to typical strategies, it is worth having a pediatric OT take a look.
Why this gets missed
Retained reflexes rarely get flagged at a standard pediatrician visit, because the checkup is not usually structured to test for them. Parents are often told to wait and see, or the behaviors get treated as purely behavioral. A trained OT can test for specific retained reflexes directly and build an integration plan targeted at the ones actually present.
What helps
Reflex integration usually involves specific, repeated movement patterns - not a single tool or toy, but a consistent home program alongside movement-rich play. Vestibular and proprioceptive tools can support this work between sessions - see our Move and Explore collection for OT-recommended options.
If several of these signs sound familiar, a pediatric OT evaluation can identify exactly which reflexes are involved and build a plan around your child specifically.
