Study Notes
Infant Nutrition and Growth
- A healthy infant doubles its birth weight in the first 4-6 months and triples it by 1 year of age.
- Infants need more energy and nutrients per pound of body weight than older children to support their rapid growth.
- Breast milk is uniquely formulated to meet the nutrient needs of newborn babies.
Lactation and Breast Milk Production
- Colostrum, produced in the first few days after birth, contains antibodies and immune system cells that can be absorbed by the infant's immature digestive tract.
- Mature milk production requires a hormonal response to suckling, triggered by prolactin and oxytocin.
- Oxytocin stimulates the "let-down" reflex, allowing milk to flow through ducts to the nipple area.
- Emotional stress and tension can block the let-down reflex, making it difficult for the infant to obtain milk.
Advantages of Breastfeeding
- Breast milk is free of bacteria and contains antibodies that reduce the risk of infections.
- Breastfed infants have lower risks of sudden infant death syndrome (SIDS), asthma, obesity, and type 1 diabetes.
- Breastfeeding promotes maternal weight loss, reduces uterine bleeding, and decreases the risk of breast cancer.
- Breast milk is easily digested, and its composition changes to meet the infant's changing needs.
Lactating Women's Nutritional Needs
- Lactating women require approximately 800 kcal per day for milk production.
- They should drink fluids frequently to maintain adequate milk volume and hydration.
- Limiting intake of alcohol- and caffeine-containing beverages is recommended, as these substances can be secreted into breast milk.
Breast Milk as a Complete Food
- Breast milk is not a complete food for all infants, as it may lack vitamins D and B-12, iron, and fluoride.
- The American Academy of Pediatrics recommends vitamin D supplementation for breastfed infants.
- Iron and zinc supplements may be necessary for breastfed infants after 6 months.
Quitting Breastfeeding Too Soon
- Many women stop breastfeeding too soon due to lack of information, support, and uncertainty about milk intake.
- Observing the infant's cues, such as fullness and six or more wet diapers per day, can help ensure adequate milk intake.
- Lactating women can express milk and preserve it for later feedings, but need comfortable, private facilities to do so.
Infant Formula Feeding
- Infant formulas are a safe and nutritionally adequate source of nutrients for babies who are not breastfed.
- Formulas are manufactured to improve digestibility and nutrient content, but lack human antibodies and immune system factors.
- Cow's milk-based and soy-based formulas have different nutrient and energy contents compared to human milk.### Infant Nutrition and Feeding
- Caregivers should provide iron-fortified infant formula for babies who are not breastfed, as not all infant formulas contain iron.
- Formula-fed babies may need a source of fluoride, but caregivers should check with their infants' physicians before providing a supplement.
Cow's Milk
- Cow's milk is not suitable for infants due to its high levels of calcium, sodium, potassium, and protein, and low levels of vitamin E, iron, and essential fatty acids.
- Cow's milk can cause intestinal bleeding and iron deficiency in infants.
- Whole milk is a major source of saturated fat in young children's diets.
- Reduced-fat forms of milk can be given to children between 1 and 2 years of age, but only as part of a diet that supplies 30% of total calories from fat.
- Children over 2 years should consume low-fat or fat-free dairy products to reduce the risk of developing cardiovascular disease.
Allergies
- Allergies are immune system responses to foreign proteins in the body.
- Allergies to proteins in foods, especially cow's milk proteins, often begin in infancy and may persist through childhood.
- Signs and symptoms of food allergies include vomiting, diarrhea, intestinal gas and pain, bloating, constipation, skin rash, runny nose, and breathing difficulties.
Introducing Solid Foods
- Solid foods should not be introduced to infants until they are about 4 to 6 months of age.
- Breastfed babies may need a dietary source of zinc and iron because their stores of the mineral are usually exhausted about 6 months after birth.
- Caregivers should continue to provide human milk or iron-fortified infant formula as the foundation of the baby's diet for the first year.
Feeding Infants
- Infants are not physically mature enough to consume solids before they are 4 to 6 months of age.
- The extrusion reflex, an involuntary response that occurs when a solid or semisolid object is placed in an infant's mouth, prevents infants from consuming solid foods before 4 to 6 months of age.
- By 6 months of age, the extrusion reflex disappears, and infants develop the physiological abilities to digest a wider range of foods.
- Weaning is the gradual process of shifting an infant from breastfeeding or bottle-feeding to drinking from a cup and eating solid foods.
Introducing New Foods
- Each new food should be introduced into a baby's diet one at a time.
- The caregiver should continue to introduce a single new food into the infant's diet over a period of several days and watch the baby for signs of allergic reactions.
- Highly allergenic foods, such as peanut butter, fish, and eggs, should be introduced into a baby's diet at around 4 to 6 months of age to prevent food allergies.
Feeding Skills
- Babies need to practice self-feeding skills, even if it means playing with food and creating messes.
- By about 10 months of age, many infants are mastering self-feeding.
What Not to Feed an Infant
- Avoid feeding an infant the following things:
- Honey, which may contain spores of Clostridium botulinum.
- Excessive infant formula or human milk, which may lead to overfeeding and a lack of nutrient-dense foods.
- Semisolid baby food in a baby bottle with an enlarged nipple opening, which contributes to overfeeding and does not help the child learn self-feeding skills.
- Candy, flavored gelatin water, or soft drinks, which provide few micronutrients and too much added sugar.
- Small pieces of hard or coarse foods, which can cause choking.
- Fruit juice, which lacks fiber content and may cause diarrhea, gas, and abdominal pain.
- Unpasteurized (raw) milk or juices, which may be contaminated with bacteria or viruses.
- Goat's milk, which is low in iron, folate, and vitamins C and D.
