Yes, at 18 months old, she shouldn't have this reflex. When a kid develops sophisticated motor abilities like sitting up, the typical timeframe for the asymmetric tonic neck reflex is typically between five and seven months.
Turning the child's head to one side causes an asymmetric tonic neck reflex. Extensor tone should rise on the side the baby's head is facing, and flexor tone should increase on the other to indicate a normal response.
This affects motor abilities. You may have poor balance when your baby bobs their head from side to side when sitting or standing. Straining to use their arms and legs to cross their midline. Unstable eye motions.
Motor issues, such as balance and coordination, bilateral coordination, writing skills, tracking, and crossing, are linked to retained ATNR.
