In infant-parent adjustment, which set of items are included?

• A. Rhythm; Behavioral repertoires; Responsivity
• B. Sleep; Diet; Exercise
• C. Income; Housing; Transportation
• D. Education; Social support; Paternal involvement

Answer: (A)

In infant-parent adjustment, the focus is on three interrelated domains that shape how families establish daily life with a new baby: rhythm, the infant’s behavioral repertoires, and parental responsivity. Rhythm refers to creating predictable patterns for feeding, sleeping, soothing, and other routines. When these routines become more stable, both infant and caregiver experience less stress and safety, because expectations are clearer and transitions smoother.

Behavioral repertoires involve recognizing the infant’s range of cues and signals—from hunger or discomfort to social engagement—and shaping responses that help the baby learn regulation. As the infant’s behaviors evolve, parents adapt their strategies to soothe, feed, and connect in ways that support development and emotional stability.

Responsivity is about how sensitively and consistently a caregiver responds to those cues. Prompt, warm, and appropriate responses foster secure attachment and help the infant develop self-regulation and trust in the caregiver.

The other options mix broader health factors (like sleep, diet, and exercise), practical resources (income, housing, transportation), or social supports (education, support networks, involvement of the father). While these elements matter for family well-being, they do not define the specific set used to describe infant-parent adjustment as clearly as rhythm, behavioral repertoires, and responsivity do.
