Care of the Newborn and Infant
Care of the Newborn and Infant
Developmental Patterns:
While children develop at different rates, it occurs in a sequential pattern.
Cephalocaudal Pattern: Growth occurs from head to toes (related to gross motor development).
Proximodistal Pattern: Growth occurs from trunk to extremities to fingers/toes (related to fine motor development).
Developmental Stages:
Infant: Birth to 12 months
Toddler: 12 – 36 months
Pre-Schooler: 36 months – 5 years
School-Aged Child: 5 – 12 years
Adolescent: 12 – 18 years
Assessment of Infant Growth and Development
Methods of Assessment:
Observation
Physical assessment
Parental report
Developmental screening tools
Timeline for Assessments:
Newborn
1 month
2 months
4 months
6 months
9 months
12 months
Well-child visits: Routine assessments are performed at these intervals.
Developmental Red Flags
Indicators of Concern:
If an infant or child fails to meet developmental milestones, this warrants further investigation and referral.
Questions to consider:
Is there a physical reason?
Is there a medical reason?
Is there a social reason?
Nurse's Role:
Nurses are crucial in preventing delays by educating, recognizing delays, and facilitating appropriate referrals.
Health Promotion through Anticipatory Guidance
Definition of Anticipatory Guidance:
Education provided to the parent about what to expect as the infant grows and develops, including:
Growth and development
Nutrition
Sleep
Safety concerns
Immunizations
Common developmental concerns
Physical Growth
Weight:
Back to birth weight by age 2 weeks
Birth weight doubles by 6 months
Birth weight triples by 12 months
Length:
Length increases by 50% in the first year.
Length is measured until 36 months.
Head Circumference:
Increases rapidly in the first 6 months.
Note: All measurements should be plotted on appropriate growth charts, and a change in percentile by 10% should be monitored.
Developmental Theory
Erikson:
Psychosocial: Focus on ego development; development of self and confidence in self.
Infant Stage: Trust vs. Mistrust
Trust develops as caregivers meet basic needs: feeding, comforting, diaper changing, playing.
Mistrust can develop if needs are not consistently met.
Piaget:
Cognitive Development: Encompasses the construction of knowledge; development of reasoning skills and learning about the world.
Infant Stage: Sensorimotor development
Infants learn about the world through their senses and motor skills.
Key Concepts:
Cause and Effect: Found in toys that make sounds or have lights.
Object Permanence: Illustrated through games like peek-a-boo.
Physical Exam of the Infant
Head:
Proportionately larger than the body.
Fontanels:
Anterior fontanel closes by 18 months.
Posterior fontanel closes by 3 months.
Head lag should disappear by 4 months of age.
Tooth eruption occurs between 6 and 8 months.
Eyes:
Strabismus is common up to 6 months of age.
Infant’s vision is not fully developed; the infant should turn their head to sound.
Respiratory:
Nasal congestion can interfere with feeding.
One may observe barrel chest and diaphragmatic breathing.
Respiratory rate can be irregular with occasional pauses and tends to be higher in infants.
Cardiovascular:
Higher heart rate (80-160 bpm).
Acrocyanosis or mottling is normal in newborns.
Gastrointestinal:
Frequency of bowel movements is not as important as consistency.
It is normal for infants to strain during bowel movements.
Musculoskeletal:
Should be symmetrical bilaterally.
Primitive reflexes (e.g., rooting, sucking, Moro, palmar grasp, Babinski) will be replaced by voluntary control as nerve cells become myelinated over time.
Infant Nutrition
Importance of Proper Nutrition:
Critical for promoting physical, developmental, and cognitive growth during infancy.
Infants experience a state of rapid growth requiring higher caloric and fat intake.
Fat intake is essential for the development of nerve cells.
Options for Feeding:
Breastfeeding:
Considered the best option for infants.
Benefits include tailored nutrition for the infant, infection protection, promotion of healthy neurological development, cost-effectiveness, and potential decrease in the incidence of atopic diseases.
The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for the first 6 months, starting Vitamin D supplementation at 2 months, continuing breastfeeding for the first two years, and introducing solids starting at 6 months.
Formula Feeding:
Formula should be iron-fortified and prepared according to directions; microwaving is discouraged.
Infants should have 6-8 wet diapers per day.
First Well-Child Visit
Timing:
The first well-child visit typically occurs between one and two weeks of age.
Assessments:
Presence of infant reflexes such as rooting, sucking, Moro reflex, palmar grasp, Babinski.
Newborn screening will be repeated.
Assess parent-infant attachment.
Provide education on car seat safety, water temperature, sleep, and infant safety practices.
Anticipatory Guidance: One Month Mark
Milestones:
Gross Motor: Arm and leg movements are symmetrical.
Fine Motor: Fingers open.
Language: Different cries.
Social/Emotional: Looks at parent, calms when comforted.
Education Topics for Parents:
Must be back to birth weight or greater.
Observation of parent-baby interaction is critical.
Topics include car seat safety, water temperatures, sleep, medications, and managing colic (inconsolable crying peaks at 6 weeks).
Anticipatory Guidance: Two Months Mark
Milestones:
Gross Motor: Lifts head and chest when prone.
Fine Motor: Brings hands together and opens/closes hands.
Language: Coos and produces gurgling sounds.
Social/Emotional: Exhibits a social smile.
Education Topics for Parents:
Repeat education on previous topics and include safety topics relevant to bath time and tummy time.
Discuss infant attachment, feeding plans considering maternal return to work, impending developments by 4 months, and choking hazards.
Anticipatory Guidance: Four Months Mark
Milestones:
Gross Motor: Supports self on elbows and forearms when prone; may roll from stomach to back; no more head lag.
Fine Motor: Explores hands and feet, grasps objects and brings them to mouth.
Language: Turns towards voices.
Social/Emotional: Laughs and mimics facial expressions.
Education Topics for Parents:
Repeat education including topics on sleep, nutrition, and medications.
Emphasize the importance of play and interaction, as well as monitoring for teething and safe sleeping environments.
Anticipatory Guidance: Six Months Mark
Milestones:
Gross Motor: Sits briefly without support (tripod position); rolls over in both directions.
Fine Motor: Transfers objects between hands and bangs objects on surfaces.
Language: Babbles; emits distinct sounds.
Social/Emotional: Looks at themselves in the mirror, recognizes familiar faces, notices strangers.
Education Topics for Parents:
Review previous education points and discuss introducing solid foods, promoting oral health, and babyproofing the home.
Anticipatory Guidance: Nine Months Mark
Milestones:
Gross Motor: Sits well without support and begins to crawl, creep, or scoot; pulls to standing.
Fine Motor: Uses a pincer grasp (three fingers & thumb).
Language: Says “Mama” and “Dada”; copies sounds, comprehends “no” and “where is it?”.
Social/Emotional: Engages in games like peek-a-boo, waves “bye-bye,” shows signs of stranger anxiety.
Education Topics for Parents:
Emphasize consistency and routine to avoid sleep regression and address nutritional needs, including safe feeding practices and avoiding choking hazards.
