Communicable Diseases in Infants
Chapter 6: Communicable Diseases - Health Protection
Understand communicable diseases affecting infants, vaccination schedules, and parent education strategies for prevention.
Infants are particularly vulnerable to communicable diseases due to their developing immune systems. Understanding transmission routes is critical for effective prevention.
Common Infant Infections
- Respiratory Syncytial Virus (RSV): Leading cause of bronchiolitis and pneumonia
- Pertussis (Whooping Cough): Severe coughing illness, dangerous for infants
- Influenza: Can cause serious complications in infants
- Group B Streptococcus: Potential cause of neonatal sepsis
Nurses play a critical role in educating families about infection prevention through handwashing, limiting exposure to sick contacts, and timely vaccination according to recommended schedules.

Developmental Milestones: First Year
Chapter 7: Developmental Milestones
Master growth charting, nutritional assessment, and specialized physical examination techniques for infants.
2 Months
- Begins to smile socially
- Makes cooing sounds
- Follows objects with eyes
- Holds head up during tummy time
4-6 Months
- Rolls over (back to front, front to back)
- Reaches for and grasps objects
- Babbles with consonant sounds
- Sits with support, then independently
9 Months
- Crawls or uses alternative mobility
- Pulls to stand
- Develops pincer grasp
- Shows separation and stranger anxiety
12 Months
- First steps with or without support
- Says 1-3 meaningful words
- Follows simple commands
- Imitates actions during play
Recognizing Developmental Delays
Chapter 8: Newborns and Infants
Recognize typical and atypical development patterns from birth to 12 months, including motor, social, and cognitive milestones.
Red Flags by Age 💥💥
While developmental variation is normal, certain signs warrant further assessment:
- By 2 months: Doesn't respond to loud sounds or track moving objects
- By 6 months: Doesn't reach for objects or bring items to mouth
- By 9 months: No babbling or reciprocal sounds
- By 12 months: No crawling, standing, or single words
Early Intervention Process
Nurses should facilitate timely referrals when concerns arise. The process typically includes:
- Standardized screening (ASQ, PEDS) at well-visits
- Referral to developmental specialists if concerns identified
- Multidisciplinary evaluation
- Development of individualized family service plan
- Implementation of therapy services
Early intervention before age 3 is critical as neuroplasticity is highest during this period, allowing for maximum developmental gains.

Erikson's Psychosocial Development: Trust vs. Mistrust
Trust vs. Mistrust: The Foundation (0-18 months)
This is Erikson's first stage, where infants develop a sense of trust when caregivers provide reliable, consistent, and affectionate care. Lack of this leads to mistrust, anxiety, and insecurity. The primary task is to develop basic trust in the world and oneself.
Nursing Implications
Understanding this stage is crucial for pediatric nurses. Infants perceive their environment through consistent care. Nurses can influence an infant's development of trust by providing predictable and responsive care, reducing anxiety associated with medical procedures, and supporting parental bonding.
Promoting Trust: Nursing Interventions
- Consistent Care: Assigning primary nurses to foster familiarity.
- Timely Responsiveness: Addressing hunger, pain, and discomfort promptly.
- Comfort Measures: Providing soothing touch, gentle handling, and verbal reassurance.
- Parental Involvement: Encouraging parents to participate in care, feeding, and comforting to maintain continuity.
Clinical Applications in Infant Care
- Hospitalization: Minimizing separation from primary caregivers; encouraging rooming-in.
- Procedures: Performing procedures quickly and efficiently, followed by comfort and reassurance.
- Feeding: Supporting parents with feeding routines (breastfeeding/bottle-feeding) and addressing challenges.
- Education: Educating parents on the importance of responsive caregiving to build trust at home.
Piaget's Cognitive Development Theory: Sensorimotor Stage (Infant Phase)
Jean Piaget's theory of cognitive development describes how children construct a mental model of the world. The first of his four stages, the Sensorimotor Stage (0-2 years), is a period where infants learn about the world primarily through their senses and motor activities. During this critical time, infants develop object permanence, cause-and-effect understanding, and goal-directed behaviors.
Substages Relevant to Infants (0-12 Months)
1
Reflexive Schemes (0-1 Month)
Infants primarily interact with their environment through innate reflexes such as sucking, rooting, grasping, and crying. These actions are not deliberate but are crucial for survival and the foundation for more complex behaviors.
2
Primary Circular Reactions (1-4 Months)
Infants begin to repeat actions that feel pleasurable and are centered on their own body, such as thumb-sucking or cooing. These actions are accidental at first but become habitual as the infant discovers how to reproduce them.
3
Secondary Circular Reactions (4-8 Months)
The infant's focus shifts from their own body to the external environment. They intentionally repeat actions that produce interesting effects in their surroundings, like shaking a rattle to hear a sound or batting at a mobile.
4
Coordination of Secondary Circular Reactions (8-12 Months)
Infants begin to combine multiple actions to achieve a goal. This is where true intentionality emerges. They also start to demonstrate early signs of object permanence, understanding that objects continue to exist even when out of sight.
Nursing Implications
Understanding these substages helps pediatric nurses tailor care to the infant's cognitive level. This includes:
- Providing age-appropriate sensory stimulation.
- Using simple language and gestures when communicating.
- Recognizing that hospitalized infants may experience developmental regression or delays due to altered sensory input.
- Involving parents in care to maintain familiar routines and provide comfort.
Assessing Cognitive Development
Nurses can assess cognitive development through observation and age-appropriate interactions:
- Observing play behaviors and how infants interact with toys (e.g., reaching for objects, shaking rattles).
- Checking for object permanence (e.g., hiding a toy and observing if the infant searches for it).
- Assessing cause-and-effect understanding (e.g., does the infant repeat an action that produces a desired result?).
- Utilizing standardized developmental screening tools (e.g., Denver Developmental Screening Test II) to identify potential delays.
Practical Applications in Pediatric Nursing Care
Applying Piaget's principles in nursing care includes:
- Creating a Safe Environment: Ensuring the infant's surroundings are free from small objects they could ingest, especially once object permanence begins to develop.
- Providing Stimulation: Offering mobiles, soft toys, colorful objects, and engaging in talking, singing, and peek-a-boo to encourage exploration and development.
- Pain Management: Using distraction techniques with age-appropriate toys or sounds during painful procedures.
- Parental Education: Educating parents about normal developmental milestones, the importance of responsive caregiving, and encouraging play that supports cognitive growth.
