the newborn

the newborn

• Average newborn weight is approximately 7.5 pounds, with a healthy range between 5 pounds, 8 ounces and 8 pounds, 13 ounces.
• Average length at birth is 19.5 inches, increasing to 29.5 inches by 12 months and 34.4 inches by 2 years.
• Infants typically lose about 5% of their body weight in the first few days as they adjust to feeding.
• Weight loss is temporary and followed by a rapid growth phase.

newborn assessments and risks

assessing the newborn

• The Neonatal Behavioral Assessment Scale (NBAS), created by T. Berry Brazelton, is a key tool for evaluating newborns globally, assisting parents in understanding their infants and comparing development across cultures.
• The assessment includes evaluating the newborn's motor development, muscle tone, and stress response.
• The APGAR test is performed at one and five minutes after birth, providing a quick assessment of the newborn's overall condition.
• Five factors are measured: heart rate, respiration, muscle tone, reflex response (Babinski reflex), and skin color, with scores ranging from 0 to 2 for each.
• A perfect APGAR score is rare, and an APGAR score of 5 or below raises concerns; the second APGAR should show improvement.

low birth weight

• Teratogens linked to low birth weight include malnutrition, cocaine, and tobacco.
• A child is classified as having low birth weight if they weigh less than 5.5 pounds (2,500 grams).
• In 2016, 8.17% of babies in the U.S. were born with low birth weight; 1.4% had very low birth weight.
• Socioeconomic inequality is correlated with low birth weight; prevalence is higher in the U.S. than in the UK, Canada, and Australia.
• Low birth weight infants struggle to maintain body temperature and are more susceptible to infections; 67% are also preterm.
• Very low birth weight (under 1,500 grams) and extremely low birth weight (under 1,000 grams) infants have a heightened risk of cerebral palsy.
• Many causes of low birth weight can be prevented with appropriate prenatal care.

premature birth

• A low birth weight in children can occur if born before 37 weeks gestation, classifying them as preterm babies.
• In 2016, 9.85% of U.S. births were preterm.
• Factors triggering early birth include disruptions to the mother’s system, such as vaginal infections or gum disease.
• Infections prompt the release of anti-inflammatory chemicals, which can trigger contractions leading to premature birth.
• Smoking and exposure to teratogens are additional risk factors for preterm birth.

anoxia and hypoxia

• Leading cause of infant brain damage is oxygen deprivation shortly after birth.
• Hypoxia: mild to moderate brain damage due to inadequate oxygen.
• Anoxia: severe brain damage from total lack of oxygen.
• Causes include umbilical cord issues, birth canal problems, blocked airways, and placental abruption.
• Both conditions can result in cerebral palsy and other medical disorders.

postpartum period

• The postpartum period starts immediately after childbirth, with the body transitioning to a non-pregnant state.
• This period, also known as puerperium, lasts about six weeks and is crucial yet often neglected for mothers and newborns, according to the World Health Organization.
• Hospital discharge can occur hours after delivery if the mother is stable, averaging one to two days for vaginal births and three to four days for cesarean sections.
• Early postnatal discharge is categorized as leaving within 48 hours of birth.
• The postpartum period has three stages: the acute phase (6-12 hours post-delivery), the subacute phase (2-6 weeks), and the delayed phase (up to 6 months).
• A significant percentage of women (87-94%) report health issues during the subacute phase, with 31% experiencing long-term health problems.
• Routine evaluations during the postpartum period are recommended by various organizations.

acute phase

• Postpartum uterine massage aids uterine contraction after placenta expulsion during the acute phase (first 6-12 hours post-childbirth).
• Nurses or midwives monitor the mother during this period due to potential complications.
• Postpartum bleeding poses the greatest health risk; uterine contraction is essential to prevent blood loss from the placental attachment site.
• The fundus of the uterus should be firm at the navel level, and healthcare providers assess the fundus and bleeding frequency.
• Uterine massage is a common practice to promote uterine contractions.
• Mothers may receive stitches for episiotomy or vaginal tearing; routine episiotomy is now less common due to research indicating selective use reduces perineal trauma.
• Healthcare professionals can provide comfort measures for perineal pain relief.

subacute postpartum period

physical recovery

• The risk of deep vein thrombosis (DVT) is elevated in the first days postpartum due to hypercoagulability, especially high for C-section patients with limited mobility.
• Prophylactic measures may include anticoagulants or compression methods for women with risk factors such as obesity, immobility, or family history of thrombotic events.
• Women with previous thrombotic events in pregnancy are generally advised to use anticoagulation.
• Vascular changes, including increased blood flow and swelling in the vagina, typically resolve within three weeks postpartum.
• The cervix narrows and lengthens gradually over several weeks.
• Postpartum infections can lead to severe complications, including sepsis and potential death if untreated.
• Approximately 33% of women experience postpartum urinary incontinence, which is more common in vaginal deliveries compared to C-sections.
• Urinary incontinence during this period heightens the risk of long-term issues; Kegel exercises are recommended for pelvic floor strength.
• Discharge from the uterus (lochia) changes color from bright red to yellow, ceasing by five to six weeks; any increase in lochia between 7–14 days may signal delayed postpartum hemorrhage.
• In the subacute postpartum period, 87% to 94% of women report experiencing at least one health problem.

infant care

• Breast milk typically begins to come in two to four days postpartum.
• Historically, non-breastfeeding women were prescribed drugs to suppress lactation, a practice that is no longer medically supported.
• Challenges with breastfeeding may occur during this period.
• Maternal sleep is often disrupted because newborns require feeding every two to three hours, including at night.
• Support from lactation consultants, health visitors, or postnatal doulas can be beneficial for new mothers.

psychological disorders

• Psychological disorders can arise during the subacute postpartum period, including postpartum depression, posttraumatic stress disorder (PTSD), and postpartum psychosis.
• Both mothers and fathers can experience postpartum mental illness, which is not uncommon.
• Early detection and treatment are essential.
• Approximately 70-80% of postpartum women may experience the "baby blues" for a few days.
• Clinical depression affects 10-20% of postpartum women, with increased risk for those with a history of mood disorders.
• The prevalence of PTSD following normal childbirth is estimated at 2.8% to 5.6% at six weeks postpartum.
• Peripartum onset depression affects women during pregnancy or within four weeks postpartum, causing anxiety, guilt, agitation, and reluctance to care for the newborn.
• While most women with postpartum depression do not physically harm their children, some struggle to be adequate caregivers.
• A study revealed that 14% of women screened positive for postpartum depression, with nearly 20% having thoughts of self-harm.

maternal-infant postpartum evaluation

• Organizations worldwide advocate for routine postpartum evaluations.
• ACOG designates the postpartum period as critical for mothers and infants.
• ACOG recommends ongoing postpartum care rather than a single visit.
• Women should contact their obstetric provider within the first three weeks postpartum for acute issues.
• A comprehensive visit is suggested at four to twelve weeks postpartum, covering mood, physical recovery, infant feeding, contraception, chronic diseases, and preventive health.
• Women with hypertensive disorders should have blood pressure checks within three to ten days postpartum, as most postpartum strokes occur within ten days post-discharge.
• Those with chronic medical and psychiatric conditions need continued management with their care provider.
• Women facing complications like hypertension or gestational diabetes should be evaluated for cardiometabolic disease due to increased cardiovascular risks.
• The World Health Organization recommends evaluations at three days, one to two weeks, and six weeks postpartum.

delayed postpartum period

• The delayed postpartum period begins after the subacute postpartum period and lasts up to six months.
• During this phase, recovery of muscles and connective tissue to pre-pregnancy state occurs.
• Childbirth complications such as urinary and fecal incontinence, painful intercourse, and pelvic prolapse may recover slowly and sometimes remain unresolved.
• Symptoms of PTSD tend to decrease significantly, from 2.8%-5.6% at six weeks postpartum to 1.5% at six months.
• Around three months postpartum, a drop in estrogen leads to significant hair loss, particularly at the temples (postpartum alopecia), but hair typically regrows without treatment.
• Postpartum thyroiditis may also develop during this period.
• Infant sleep patterns generally improve, leading to better maternal sleep quality.
• Long-term health issues persist in 31% of women after the delayed postpartum period.
• Continuous physical and mental health evaluations, risk factor identification, and preventive care are recommended.

cultures

• Postpartum confinement is a recovery system after childbirth, lasting from one month to up to 100 days.
• It includes traditional health beliefs, rituals, and taboos, historically known as "lying-in," focused on bed rest.
• The practice is documented in various cultures, notably in China as "Sitting the month."
• In South Korea, traditional postnatal care, called sanhujori, is widely practiced for proper recovery.
• Sanhujori has evolved from reliance on family to include modern services, with over 500 maternity hotels operating in Korea.

benefits of breastfeeding

• Breast milk is the ideal diet for newborns, particularly due to the nutritional content of colostrum, which is crucial for building the infant's immune system.
• Colostrum is rich in nutrients and changes to thinner breast milk by the third to fifth day after birth, providing the necessary balance of fats, sugars, and proteins for physical and neurological development.
• Breast milk's iron is more easily absorbed than that from supplements, aiding in disease resistance and digestive efficiency compared to formula, and facilitating the transition to solid foods.
• Research indicates that breastfeeding is linked to cognitive development, with low birth weight infants showing greater benefits in brain development and IQ compared to formula-fed peers.
• Breast milk is easier to digest than formula, leading to fewer digestive issues and lower rates of infections and chronic conditions like asthma, obesity, and childhood leukemia.
• It is advised that mothers breastfeed exclusively for at least six months and continue breastfeeding throughout the first year as endorsed by health organizations.
• Mothers reap benefits from breastfeeding too, including reduced risks of breast and ovarian cancer, improved uterine recovery, and lower likelihood of developing Type 2 diabetes.

• Most mothers in the U.S. stop breastfeeding around 6-8 weeks to return to work.
• Breast milk can be expressed and stored for later feeding, but external support for breastfeeding is often insufficient.
• Some workplaces offer flexible schedules and accommodations for breastfeeding, while many do not.
• Public support for breastfeeding varies significantly, with Canada showing higher rates of breastfeeding and longer recommended duration (up to 2 years).
• Canadian facilities provide better support for breastfeeding mothers compared to those in the U.S.
• Breastfeeding offers nutritional and health benefits and is cost-effective, saving families over $1,500 annually compared to formula feeding.

when breastfeeding doesn’t work

• Mothers may be unable to breastfeed for multiple health, social, and emotional reasons.
• Situations where breastfeeding may not occur include:
- Adoption of the baby
- Mother's transmissible diseases (e.g., tuberculosis, HIV)
- Mother's drug addiction or harmful medication use
- Infant from a family with two fathers without available surrogate breastfeeding
- Attachment issues between mother and baby
- Both mother and baby in the ICU post-delivery
- Insufficient breast milk production by the mother
• While breastfeeding is thought to promote bonding and emotional development, research indicates that breastfed and bottle-fed infants emotionally adjust similarly.
• This finding benefits mothers unable to breastfeed and reassures fathers who may feel excluded.

cultural differences

• Breastfeeding rates are higher among immigrants than non-immigrants (Dennis et al., 2019).
• Mothers born in the U.S. are less likely to breastfeed than foreign-born mothers (Gibson-Davis & Brooks-Gunn, 2006).
• This phenomenon may contribute to the immigrant paradox (Coll & Marks, 2012).
• Despite often having a lower socioeconomic status (SES), immigrant children show higher breastfeeding rates and better health outcomes.
• Children of immigrants tend to have greater long-term educational achievements compared to those born to women of the same ethnic and socioeconomic group.
• These findings illuminate the strengths immigrants bring to their communities and suggest areas for further research.

global considerations and malnutrition

• In the 1960s, formula companies promoted infant formula in developing countries, leading to a misconception of its superiority over breast milk.
• Formula can be healthy if mixed with clean water and sanitized bottles, but many regions lacked these necessities, resulting in health issues for infants, such as diarrhea and dehydration.
• Currently, many hospitals are prohibiting formula sample distribution to promote breastfeeding, although mothers often need education about its benefits.
• The World Health Organization recommends initiating breastfeeding within one hour of birth, exclusive breastfeeding for the first six months, and continued breastfeeding alongside solid foods until at least two years of age.
• In the U.S., approximately 9 million children are malnourished, with many suffering from milk anemia, linked to excessive cow's milk consumption and insufficient iron intake.
• Iron deficiency can affect mental, motor, and behavioral development. It is suggested that a diverse, iron-rich diet and limited cow's milk intake can help prevent iron deficiency anemia.
• Children in developing countries or war-torn areas face significant malnutrition risks, including infantile marasmus (starvation from caloric deficiency) and kwashiorkor (protein deficiency), with breastfeeding providing a protective factor against malnutrition.
