My Baby Still Has the Spinal Galant Reflex
The short answer
The spinal galant reflex causes your baby to curve their trunk toward the side that is stroked along the spine. It normally integrates by 3-9 months. Persistence beyond 9 months may affect sitting posture, potty training (sensitivity to clothing against the back), and concentration. If you notice your baby still curves strongly when their back is stroked after 9 months, mention it to your pediatrician.

By Age
What to expect by age
The spinal galant reflex is normal at this age. When you stroke along one side of your baby's spine, they curve toward that side. This reflex is thought to help babies wiggle through the birth canal during delivery.
The reflex should be weakening. Your baby may still respond to back stroking but the response should be less dramatic. If the reflex is still very strong, it may affect your baby's ability to lie flat comfortably.
The galant reflex should be integrated or very weak by now. If it persists strongly, it may contribute to difficulty sitting still, sensitivity along the back, and postural issues.
Persistence of the galant reflex at this age warrants evaluation. Physical or occupational therapy can help integrate retained reflexes. Some children with persistent galant reflex are fidgety and have difficulty sitting comfortably.
What Should You Do?
When to take action
- Your baby is under 6 months and responds to back stroking.
- The response is weakening over time.
- Your baby is not bothered by clothing or lying on their back.
- The galant reflex persists beyond 9 months.
- Your baby seems very sensitive to back touch.
- Your baby is very fidgety and cannot sit comfortably.
- The reflex is getting stronger.
- Multiple reflexes are persisting beyond their expected timeframes.

Related Physical Concerns
My Baby's Primitive Reflexes Are Not Integrating
Primitive reflexes are automatic movements present at birth that should gradually integrate (disappear) during the first year as your baby develops voluntary movement control. If reflexes persist beyond their expected timeframe, it may indicate neurological immaturity or developmental concerns. Your pediatrician checks reflexes at well visits.
Poor Trunk Control
Trunk control - the ability to hold the torso upright and stable - develops progressively throughout the first year. It is essential for sitting, crawling, standing, and walking. Babies build trunk control through tummy time, supported sitting, and active play. If your baby seems unusually floppy in the trunk or slumps significantly when sitting, your pediatrician can assess whether their core strength is developing as expected.
My Baby Seems to Use One Side More Than the Other
Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.
My Baby Only Army Crawls
Army crawling (also called commando crawling) is a completely valid and normal way for babies to move. Many babies army crawl for weeks or even months before transitioning to hands-and-knees crawling, and some skip hands-and-knees crawling entirely. What matters is that your baby is independently mobile and exploring their environment.
One Side of My Baby's Body Moves Differently
Babies should generally use both sides of their body equally. If one side consistently moves differently, is weaker, stiffer, or less coordinated, this warrants evaluation. Asymmetric movement can indicate hemiplegia (cerebral palsy affecting one side), brachial plexus injury, or other neurological conditions that benefit from early therapy.
My Baby Crawls Unevenly
While some variation in crawling patterns is normal, consistently favoring one side or dragging one limb while crawling warrants attention. Babies should use both arms and both legs relatively equally when crawling. Persistent asymmetry could indicate muscle tone differences, hip issues, or neurological concerns that benefit from early evaluation.
