Early research suggests that if a 6-month old baby
has "head lag," or weak head and neck control, it may be an early sign of autism or another language/social developmental delay.
The test is simple –
babies who are lying on the floor are pulled up into a sitting
position. If the baby's head is not moving forward as you pull the baby
up, it's a sign of weak head and neck control.Researchers already know that head lag could be an early sign that a child's nervous system is not developing correctly. They've seen this in children with cerebral palsy and preterm infants, for example. But so far it had not been documented in children with autism.
