Situation: The nurse works in the infant and toddler section of the pediatric ward of a provincial hospital, where a parent or grandparent stays at each child's bedside as a watcher.

The mother of a 3-month-old boy can stay only during the day; his grandmother, who helps care for him at home, will stay at night. The mother shares her plans for the nights. Which plan is BEST for his emotional development at this age?

1. "I'll leave a shirt with my scent in his crib so he won't miss me at night."
2. "He is too young to miss me yet, so any nurse can settle him at night."
3. "His grandmother and I will answer his cries quickly and the same way." **✔ 정답**
4. "We'll feed him every 4 hours by the clock so that nights are easier."

**정답: 3**

## 해설

Two ideas apply together. At 3 months, trust vs. mistrust is built when a small number of familiar caregivers meet needs promptly and consistently, so the mother and grandmother should respond to his cries quickly and in the same way. Separation anxiety and the use of comfort objects appear only in the second half of the first year, so a scented shirt meets a need he does not yet have, while "any nurse" and clock feeding undermine consistent, responsive care.

## 심화 해설

Core developmental task at 3 months

A 3-month-old infant is in the earliest phase of Erikson’s trust versus mistrust stage. Trust is not built through dramatic gestures or rigid schedules, but through repeated experiences in which a small number of familiar caregivers recognize distress and respond promptly and consistently. When the mother and grandmother answer cries quickly and in the same way, the infant learns that his signals produce a predictable, comforting response from a known person. At this age, emotional security depends on responsive caregiving from a stable few, not on the number of caregivers or on objects left in the crib.

Why the other options are not best

Option 1 describes a scented shirt as a comfort object. Watch out! The capacity to use a transitional or comfort object, and the distress of separation anxiety, typically emerge in the second half of the first year, not at 3 months. The infant is not yet developmentally able to self-soothe by associating an object with the mother’s presence. Option 2 assumes the infant is too young to miss the mother, but this misses the point: the issue is not missing a specific person in a cognitive sense, but whether care is consistent and familiar. Rotating “any nurse” fragments the caregiving experience and weakens the predictability the infant needs. Option 4 imposes clock-based feeding every 4 hours. Key point! Scheduled feeding can override the infant’s hunger and comfort cues, reducing the contingent responsiveness that builds trust. Cue-based feeding and cue-based comforting are more aligned with the developmental task at this age.

How the evidence deepens the explanation

The research on caregiver sensitivity supports the idea that responsiveness is not a fixed trait but varies with everyday demands and distractions [1]. This means the plan must be practical enough to preserve responsiveness across day and night shifts. Having the mother and grandmother use the same approach reduces the chance that the infant receives mixed or delayed responses when caregiving changes hands. Consistency between two familiar caregivers protects the infant from the natural variation in sensitivity that occurs when caregivers are tired or distracted.

The physiological findings reinforce the behavioral plan. Caregiver holding, rather than vocalizing alone, supports real-time vagal regulation in infants following distress . This does not mean the grandmother must hold the infant constantly, but it does suggest that close, calming physical contact during distress is a key part of responsive care. A scented shirt cannot provide this regulatory support. The infant’s parasympathetic recovery after crying is supported by the caregiver’s physical presence and responsive touch, not by an object or by a delayed, scheduled response.

The attachment and mentalizing literature also supports the long-term importance of early caregiving patterns. Early attachment relationships form the foundation for later socio-cognitive capacities such as mentalizing , and insecure attachment patterns are linked to more maladaptive schemas across populations . These are long-range outcomes, but they reinforce why the nursing priority at 3 months is to protect a stable, responsive caregiving dyad rather than to introduce convenience strategies that reduce contingent care.

| Plan | Developmental fit at 3 months | Main problem |
| --- | --- | --- |
| Scented shirt in crib | Comfort objects emerge later in infancy | Addresses a need the infant does not yet have |
| Any nurse can settle him | Trust requires familiar, consistent caregivers | Fragments caregiving and reduces predictability |
| Grandmother and mother respond quickly and the same way | Matches trust versus mistrust task | None; this is the best plan |
| Feed every 4 hours by the clock | Responsive, cue-based care is needed | Overrides infant cues and delays comfort |

Clinical reasoning for the nurse

When a parent asks about nighttime care, the nurse should assess whether the plan preserves contingent responsiveness and caregiver consistency. The best plan is the one in which the two familiar caregivers agree on how to read and answer the infant’s cues, because that is what builds the expectation that distress will be met with comfort. A shirt, a rotating nurse, or a fixed clock cannot substitute for a familiar person who responds quickly and predictably.References (research sources)

## 임상 시나리오

Building Trust at 3 MonthsConsistent, familiar caregivers matter more than objects or schedules
At 3 months, the infant is in Erikson's trust versus mistrust stage. Emotional security develops when a small number of familiar caregivers respond to cries promptly and consistently. The mother and grandmother should answer cries quickly and in the same way to create predictable, comforting care.

Transitional objects such as a scented shirt and separation anxiety emerge in the second half of the first year, not at 3 months. A shirt with the mother's scent meets a need the infant does not yet have.

Rotating any nurse fragments the caregiving experience and weakens predictability. Clock-based feeding every 4 hours overrides hunger and comfort cues, reducing the contingent responsiveness needed for trust.

CautionDo not rely on comfort objects or rigid feeding schedules at this age. The priority is a stable, familiar caregiver who reads and responds to the infant's cues consistently.

## 핵심 개념

- **Trust vs. mistrust** — Erikson's first psychosocial stage (birth to 1 year) where consistent, responsive care from familiar caregivers builds basic trust.
- **Transitional object** — A comfort item such as a blanket or shirt that helps a child self-soothe; typically emerges in the second half of the first year.
- **Separation anxiety** — Distress when separated from primary caregivers; appears later in infancy, not at 3 months.
- **Responsive caregiving** — Recognizing and promptly answering an infant's cues such as crying, which builds predictability and emotional security.
- **Contingent responsiveness** — Care that is directly linked to the infant's signals rather than a fixed schedule, supporting trust development.
