Chapter Outline

 

Physical Growth

        Measuring and Predicting Growth

• Growth during the first 3 years is faster than at any other point after birth.
• Breastfed babies tend to be longer and leaner than babies who are not breastfed.
• Growth charts from the Centers for Disease Control and Prevention describe how samples of U.S. infants and children grew, whereas new growth charts from the World Health Organization are based on studies of exclusively breastfed infants from six different countries.

        Failure to Thrive

• Most cases of failure to thrive are caused by a lack of adequate nutrition due to feeding problems, health problems, or oral or motor conditions.
• Some children with psychosocial short stature may be underweight and extremely short for their age due to neglect or emotional and psychological trauma.
• For children with psychosocial short stature, being moved to a new, caring environment often triggers a dramatic catch-up growth spurt.

Brain Development

• Brain development begins prenatally with the production and migration of neurons.
• Postnatal brain growth primarily consists of the interconnection of neurons and the formation of synapses involving axons and dendrites.
• Different regions of the brain develop most rapidly at different ages.
• Pruning of synapses begins at the end of the first year of life.
• Experience activates neurons, and repeated experiences strengthen neural networks.

        Maltreatment, the Brain, and Shaken Baby Syndrome

• Animal experiments and clinical studies of children suggest that early adversity and stress harm the developing brain.
• Neurobiological components of the stress-response system develop and become organized in the early months of life, meaning that infants are capable of experiencing fear, anxiety, and psychological stress.
• The infant’s brain is especially vulnerable to injury caused by shaken baby syndrome.
• Abusive head trauma due to shaken baby syndrome is the leading cause of infant death from injury in the United States.

 

Health and Safety

        Newborn Screening

• All U.S. newborns are screened for PKU, congenital hypothyroidism, and galactosemia.
• All newborns should also be screened for congenital hearing loss.

        Screening for Lead Poisoning

• Untreated lead poisoning can result in brain damage, behavior problems, learning disabilities, seizures, and even death.
• Low-income, urban, and African American children have the highest rates of lead poisoning.

        Infant Mortality

•        Infant mortality rates in the United States vary by race and ethnicity as well as mother’ age, education, marital status, and health.
• Globally, infant mortality is linked to poverty, inadequate prenatal care, complications of pregnancy, malnutrition, lack of clean drinking water, and low rates of immunization against childhood illnesses and diseases.

        Common Illnesses and Immunizations

• Infants’ immature immune system, and the tendency to place their hands, toys, and other objects in their mouth, makes them especially vulnerable to contagious illnesses.
• Immunizations against childhood illnesses and diseases save lives and protect health.

        Accidental Injuries

• The major causes of death in infancy and early childhood are unintentional, preventable injuries.
• As babies and toddlers develop and gain new skills, parents and caregivers need to be aware of and anticipate new hazards.

        Sudden Infant Death Syndrome

• Sudden infant death syndrome (SIDS) is the leading cause of death in infants between 1 month and 1 year of age.
• Place all healthy babies on their back to sleep and avoid the use of soft bedding.
• Other risk factors are maternal smoking, sleeping in an overheated room, and bed sharing.
• Some SIDS deaths may be caused by an abnormality in a portion of the brain.

Nutrition and Feeding

        Nutritional Requirements in Infancy

• Children under the age of two years need more fat in their diet than any other age group.

        Breast Milk/Infant Formula

• Until the age of about 4 to 6 months, infants can get all of their nutritional requirements through breast milk or formula.
• According to most experts, human milk is the preferred form of feeding for infants.
• The Baby-Friendly Hospital Initiative and other health education campaigns have increased breastfeeding rates and duration.
• Infant formula available today is the best alternative to breast milk that has ever existed.
• Experts recommend that parents not initiate complementary feeding until the baby is 4 to 6 months of age.

        Nutritional Requirements in Toddlerhood

• Overweight and obesity are growing concerns in the United States, even among young children.
• Many toddlers do not get the recommended variety of minerals and nutrients.

        The Problem of Malnutrition

• Worldwide, many infants and young children suffer from problems related to an insufficient amount of food or an inadequate intake of essential nutrients, protein, and calories.
• Infants and young children are more susceptible than older children to growth impairment caused by protein-energy malnutrition.

Lecture Launcher: Staying Safe and Healthy at Home and in Child Care

From a health and safety perspective, which is safer – home or child care?  Although students may have strongly held preconceptions about this question, neither the home nor the child care setting are inherently safe or risky.  The articles listed below can be used in a lecture highlighting the importance of remaining vigilant to possible hazards in the places where infants and toddlers spend their time. These sources support the notion that, in addition to setting up an environment in which infants and toddlers are free to explore, parents and other caregivers need to monitor young children and anticipate potential problems before they occur.

 

Morrongiello, et al. (2004a & 2004b) have studied toddlers’ in-home injuries.  In two back-to-back articles, they report their findings about the context, correlates, and determinants, as well as parental strategies, and their efficacy, for managing child injury risk.  Their studies suggest that many parents whose toddlers sustain injuries at home overestimate their young children’s ability to follow rules and prohibitions when they are not closely supervised.

 

The American Academy of Pediatrics maintains a webpage (http://www.healthychildcare.org/articles.cfm) with full-text articles about safety awareness and health promotion in child care settings.  The articles include:

 

Copeland, K., Duggan, A., & Shop, T. (2005). Knowledge and beliefs about guidelines for exclusion of ill children from child care. Ambulatory Pediatrics, 5, 365-371.

 

Gupta, R., Shuman, S., Taveras, E., Kulldorff, M., & Finkelstein, J. (2005). Opportunities for health promotion in child care. Pediatrics, 116, 499-505.

 

Moon, R.Y., Aird, L., & Kotch, L. (2006). State child care regulations regarding infant sleep environment since the Healthy Child Care America – Back to Sleep Campaign. Pediatrics, 118, 73-83.

 

Moon, R.Y., Patel, K.M., & Schaefer, S.J.M. (2000). Sudden infant death syndrome in child care settings. Pediatrics, 106, 295-300.

Hands-On Learning Activities

 

1. Newborn Screening: To learn more about current practices and initiatives, visit the website of the Centers for Disease Control and Prevention (http://www.cdc.gov/nceh/dls/newborn_screening.htm) and the National Center of Medical Home Initiatives for Children with Special Needs (http://www.medicalhomeinfo.org/screening/newborn.html). Finally, visit the website for your own state (http://www.medicalhomeinfo.org/screening/index.html) in order to find out how many congenital conditions or disorders are included in mandatory newborn screening.

 

2. Play It Safe: The U.S. Consumer Product Safety Commission (CPSC) maintains a website (http://www.cpsc.gov/) with information about recalled or dangerous toys and products for infants and children. As you check out the safety tips posted there (http://www.cpsc.gov/tips.html), notice how many are relevant to children from birth to age three.  On another CPSC webpage (http://www.cpsc.gov/cpsclist.asp), consumers can sign up to receive email alerts about recalled products, including those pertaining to infants and children.  Would you recommend that parents of infants and toddlers subscribe to this service?  Why or why not?

 

Suggested Videos and DVDs	Description
“Infant Massage: The Power of Touch,” (1990/2003, 47 mins), V.I.E.W. Video.	This video features step-by-step instructions in massage techniques for babies. It also includes explanations as to how massage can help an infant’s eating and sleeping habits and how massage encourages communication development. Highlights contain massage exercises for premature babies and children with cholic and guidance as to when infant massage should not be used.
“Portrait of Promise: Preventing Shaken Baby Syndrome,” (1995, 11 mins), Midwest Children’s Resource Center at Children’s Health Care and The Junior League of St. Paul, Inc.	Nationally recognized child abuse specialist Dr. Carolyn Levitt addresses the injuries that can occur when a baby or young child is violently shaken due to inconsolable crying, or anger and frustration of the parent or caregiver. She gives insight into the prevention of this serious form of child abuse.
“The Secret Life of the Brain: The Baby’s Brain: Wider than the Sky,” (2001, 58 mins), PBS.	Examines how the brain builds itself from conception through the first year of life. Neurobiologists study the intricate relationship between genes and the environment, and a study is done to find out if the difficulties premature babies have paying attention and learning later in life can be overcome by providing an environment that imitates the womb.  Also shows the case of an infant with a congenital cataract as an example of a critical period in development.
