The STNR is not a primitive reflex. In other words, a baby is not born with it. The STNR is a postural reflex–its purpose to start the baby in its goal to get vertical so it can walk-to develop posture.The STNR emerges around 6-9 months of life and should be integrated by eleven months. It helps inhibit the TLR. It allows a child to get up on all fours. It must be inhibited fully for a child to creep with all four limbs. Many children who skip the creeping/crawling stage have a fully active STNR reflex.
Creeping (this is what most people call “crawling”–on all four limbs) is one of the most important movement patterns babies experience. It is vital in the development of the near point vision system where babies see and work with objects in their midfield. It is needed for visual tracking and for writing on a straight line.
