The Moro reflex is a baby's internal alarm system to protect against danger. It is activated when startled by noise, movement, or falling sensations. As the reflex diminishes, adults develop the normal startle response, allowing for postural control without losing infant control.
The Moro reflex, present after six months, can cause an uncontrolled overreaction, overriding newly acquired decision-making skills. This creates a physical environment where certain senses are heightened, making it difficult for a child to cope with everyday normalities.
