Promoting and Protecting the Health of

Infant, Toddler and Preschool Populations

Traditionally, pregnancy has been divided into three periods called trimesters, each of which lasts about 3 months.

Each trimester includes certain landmarks for developmental changes in the mother and the fetus.

During the intrauterine stage of development, the embryo or fetus relies on the maternal blood flow through the placenta to meet its basic survival needs.

The health of the mother is essential for proper growth and development.

Neonates and infants

(Birth to 1 year)

Physical Development

A neonate’s basic task is adjustment to the environment outside the uterus, which requires breathing, sleeping, sucking, eating, swallowing, digesting, and eliminating.

At birth, most babies weigh from 2.7 to 3.8 kg, babies usually gain weight at the rate of 150 to 210 g weekly for 6 months.

Exclusive breast-feeding in the first 4 to 6 months may be helpful in preventing excessive weight gain

LENGTH

The average length of a European American newborn in the United States is about 50 cm. Female babies are, on average, smaller than male babies.

HEAD AND CHEST CIRCUMFERENCE:

At birth the average infant’s head circumference is 35 cm and generally varies only 1 or 2 cm.

The chest circumference of the newborn is usually less than the head circumference by about 2.5 cm.

VISION

The newborn can follow large moving objects and blinks in response to bright light and sound. The pupils of the newborn respond slowly, and the eyes cannot focus on close objects.

HEARING

Newborns with intact hearing will react with a startle to a loud noise, a reaction called the Moro reflex. Within a few days, they are able to distinguish different sounds.

Reflexes of the newborn are unconscious, involuntary responses of the nervous system to external and internal stimuli. Reflexes normally present at birth are the sucking, rooting, Moro, palmar grasp, plantar, tonic neck, stepping, and Babinski reflexes

Health Promotion Guidelines for Infants HEALTH EXAMINATIONS

Screening of newborns for hearing loss at 1 month of age, diagnosis by 3 months of age, with intervention and treatment by 6 months of age

• Physical exam at 2 weeks and at 2, 4, 6, 9, and 12 months PROTECTIVE MEASURES

• Immunizations: diphtheria, tetanus, acellular pertussis (DTaP), inactivated poliovirus vaccine (IPV), pneumococcal (PVC), Haemophilus influenzae type B (HIB), hepatitis B (HepB), hepatitis A (HepA), rotavirus, and influenza vaccines as recommended.

Varicella and measles-mumps-rubella (MMR) are not given before 12 months of age.

• Fluoride supplements for infants over 6 months of age if there is inadequate water fluoridation (less than 0.3 parts per million)

Screening for tuberculosis

• Screening for metabolic conditions including phenylketonuria (PKU)

• Prompt attention for illnesses

• Appropriate skin hygiene and clothing

INFANT SAFETY

• Importance of supervision

• Car seat, crib with a firm mattress, playpen, bath, and home environment safety measures

• No stuffed animals, pillows, or blankets in the crib

• Position the infant on the back for sleep

• Feeding measures (e.g., avoid propping bottle)

• Provide toys with no small parts or sharp edges

• Eliminate toxins in the environment (e.g., tobacco, chemicals, radon, lead, mercury)

• Use smoke and carbon monoxide (CO) detectors in home

NUTRITION

• Exclusive breast-feeding to 4 to 6 months

• Solid foods between 4 and 6 months

• Need for iron supplements at 4 to 6 months

• Continued breast-feeding to age 12 months

• Breast-feeding and bottle-feeding techniques

• Formula preparation

• Feeding schedule

ELIMINATION

• Characteristics and frequency of stool and urine elimination

• Diarrhea and its effects

REST/SLEEP

• Establish routine for sleep and rest patterns

SENSORY STIMULATION

• Touch: holding, cuddling, rocking

• Vision: colorful, moving toys

• Hearing: soothing voice tones, music, singing

• Play: toys appropriate for development

TODDLERS (1 TO 3 YEARS)

Toddlers develop from having no voluntary control to being able to walk and speak. They also learn to control their bladder and bowels, and they acquire a wide variety of information about their environment.

WEIGHT

Two-year-olds can be expected to weigh approximately four times their birth weight.

The 3-year-old should weigh about 13.6 kg.

HEIGHT

A toddler’s height can be measured as height or length. Height is measured while the toddler stands between 2 and 3 years it slows to 6 to 8 cm

Health Risks: Toddlers experience significant health problems due to injuries, visual

problems, dental caries, and respiratory and ear infections.
