Final answer:
Parents can detect overstimulation in infants by observing signs like turning away the face, stiffening, and extending extremities and fingers. Careful observation of these signs can help ensure infants' comfort and well-being.
Step-by-step explanation:
Understanding overstimulation in infants is important for parents to ensure the well-being of their child. When a baby experiences overstimulation, they might show signs such as turning their face away or displaying physical responses like stiffening and extending their extremities and fingers. Newborns have a sensitive sense of touch which can be both comforting through cuddles and potentially overwhelming with excessive stimuli. Indicators of overstimulation may seem subtle and thus require careful attention from caregivers. Babies might also exhibit signs of distress like excessive crying or sensitivity to light as presented in the case of one-year-old Olivia brought to the emergency room.
