A nurse in a clinic is assessing a 9-month-old infant. Which of the following findings requires further intervention?

A. The Doll's eye reflex is expected to be negative in older infants. It is present in newborns but should be absent by 2 months of age. B. The Crawl reflex, which involves the infant moving forward when placed on their stomach, should disappear by 6-8 months. A negative reflex at 9 months is expected. C. The Babinski reflex, where the toes fan out when the sole of the foot is stroked, is normal in infants up to 12-18 months. D. The Moro reflex, or startle reflex, should disappear by 4-6 months of age. A positive Moro reflex at 9 months indicates a delay in neurological development and requires further evaluation.
