The ATNR (asymmetrical tonic neck reflex) shows up early in infancy. When a baby turns their head, the arm and leg on that side extend while the opposite side bends. This reflex helps with early coordination and visual development. But it’s meant to integrate as the brain matures. When ATNR remains active, the body may still want to move with the head – even during tasks that require stability. This can affect: • handwriting and pencil control • crossing midline • hand dominance • eye-hand coord

The ATNR (Asymmetrical Tonic Neck Reflex) and STNR (Symmetrical Tonic Neck Reflex) are primitive reflexes that help infants develop motor skills. IF REFLEXES RETAINED( doesn't integrated ):- What it means: If these reflexes don't disappear at the expected times, it is called a retained primitive reflex. Why it matters: Retained reflexes can interfere with motor skills, posture, and coordination, affecting activities like crawling, catching, and writing. #autism #earlyexplorers #photoshoot #mumma
