Which of the following statements is true regarding the sensitivity of a caregiver to an infant's cues?

The statement regarding caregivers being able to notice tension and heart rate through touch is true because touch is a vital aspect of how caregivers interact with and respond to infants. Infants communicate their needs and emotional states through various cues, including physical tension, heart rate changes, and other non-verbal indicators. Sensitive caregivers can use their tactile senses to pick up these subtle changes. For example, when a caregiver holds an infant, they can feel the infant's muscle tension or differences in heartbeat, which may signal distress or comfort. This attunement allows caregivers to respond appropriately to the infant’s needs, reinforcing attachment and trust.

Furthermore, infants are responsive to physical touch; they thrive on skin-to-skin contact, which is crucial for their emotional and physical well-being. This sensitivity to touch enhances the bond between the caregiver and the infant and supports the infant's overall development.
