Human beings go through a very complex development process beginning in utero and continuing on for years. Infant Reflexes, or “primitive reflexes” (called this because they are the first to develop) are part of this incredibly important development. These primitive reflexes help the baby develop movement patterns, which in turn spur brain development. They also prepare the baby for the birthing process. Primitive reflexes are present before and at birth and integrate, or disappear, during the first year of life. These reflexes must fully integrate to allow for the development of the postural reflexes.

 

Postural reflexes allow babies to move from horizontal to vertical, standing on their feet and being mobile. If a child does not complete a reflex stage, like they never scooted backwards or never crawled; or if the stage wasn’t completed correctly (crawled in an odd position or for a very short period of time), there will be lifelong consequences. Continued development of the brain is dependent upon completion of these early steps and of integration of these reflexes.

 

 

Let’s look at the order in which the reflexes develop (this is not a comprehensive list). You can click on any reflex to read more about it:

 

Moro Reflex: Develops 8-10 weeks in-utero

 

Palmar & Hands Grasping Reflex: Develops 11 weeks in utero

 

Tonic Labrinthyne Reflex (TLR) Forward: 4 months in utero

 

Asymmetrical Tonic Neck Reflex (ATNR): 5 months in utero

 

Spinal Galant: 5 months in utero

 

TLR Backward: during birth process

 

Babinksi Reflex: 1st month after birth

 

Landau Reflex: 2nd month after birth

 

Amphibian Reflex: 3-4 months

 

Symmetrical Tonic Neck Reflex: 6-8 months
