From the Guidelines

A 5-week-old well child visit should include a comprehensive physical examination, growth measurements (weight, length, and head circumference), and developmental assessment, with a focus on monitoring the infant's growth trajectory and ensuring proper development during this period of rapid change. The healthcare provider will review feeding patterns, sleep habits, and elimination patterns. Vaccinations typically administered at this visit include the second dose of Hepatitis B vaccine if not already given at birth, as recommended by standard pediatric guidelines 1. The provider will screen for jaundice, check fontanelles, assess muscle tone, and evaluate primitive reflexes. Parents should be prepared to discuss any concerns about feeding (breastfeeding or formula), sleep patterns, crying, and bowel movements.

Key Assessments and Interventions

  • Review of clinical features and confirmation of diagnosis, if not done previously 1
  • Review of routine health maintenance, including growth measurements and developmental assessment
  • Vision screening, including assessment for strabismus and other concerns, with referral to a pediatric ophthalmologist or an ophthalmologist with special expertise and experience with infants with disabilities, if necessary 1
  • Administration of recommended vaccines, unless there are specific contraindications 1
  • Anticipatory guidance on safety measures, such as proper car seat use, avoiding secondhand smoke, and preventing falls

Developmental Milestones

The visit will also assess developmental milestones appropriate for this age, including:

  • Ability to briefly lift the head when placed on stomach
  • Ability to follow objects with eyes
  • Ability to respond to sounds These assessments are crucial for monitoring the infant's growth trajectory and ensuring proper development during this period of rapid change. According to the American Academy of Pediatrics (AAP), vision screening should be performed at all well-child visits for children starting in the newborn period to 3 years, including ocular history, vision assessment, external inspection of the eyes and lids, ocular motility assessment, pupil examination, and red reflex examination 1.

From the FDA Drug Label

The FDA drug label does not answer the question.

From the Research

Necessary Assessments for a 5-Week-Old Infant

  • A complete history during the well-child visit includes information about birth history; prior screenings; diet; sleep; dental care; and medical, surgical, family, and social histories 2
  • A head-to-toe examination should be performed, including a review of growth 2
  • Screening for postpartum depression in mothers of infants up to six months of age is recommended 2

Necessary Interventions for a 5-Week-Old Infant

  • Immunizations should be reviewed and updated as appropriate 2
  • Developmental surveillance at each visit, with formal developmental screening at nine, 18, and 30 months and autism-specific screening at 18 and 24 months 2
  • Car seats should remain rear facing until two years of age or until the height or weight limit for the seat is reached 2
  • Fluoride use, limiting or avoiding juice, and weaning to a cup by 12 months of age may improve dental health 2
  • Anticipatory guidance and educational counseling during well-child visits can be improved using computerized tutorials 3
  • Parents should be counseled on proper sleep position, nutrition, and car seat use 3

Components of Well-Child Care

  • Repeated examinations of healthy children during health supervision visits are used to assess biomedical health, development, behavior, and family functioning 4
  • Well-child care serves to provide parent education through age-appropriate counseling referred to as anticipatory guidance 4
  • The delivery of well-child care includes a mean of 7.2 health supervision/anticipatory guidance topics addressed per visit 5
  • Clinicians addressed a mean of 42% of Bright Futures-recommended age-specific health supervision/anticipatory guidance topics 5
