Study Notes

Overview of Infant Feeding

Human milk is the preferred source of nutrition for infants, recommended for the first 6 months of life by the AAP.
Breastfeeding is encouraged for at least the first year and beyond, with notable benefits for infant neurodevelopment.

Physiology of Lactation

Hormones such as estrogen and progesterone play crucial roles in mammary gland development during puberty and pregnancy.
Prolactin stimulates milk production postpartum, while oxytocin is responsible for milk ejection during breastfeeding.

Reflexes Involved in Lactation

Sucking reflex occurs when the nipple contacts the palate, leading to milk intake.
Rooting reflex helps the infant locate the breast by moving its head toward stimuli like touch or smell.
Letdown reflex is triggered by the infant's sucking or psychological cues and involves the release of oxytocin.

Stages of Lactation

Colostrum is produced in the first few days post-delivery, rich in nutrients, immunoglobulins, and protective factors.
Transitional milk occurs between colostrum and mature milk.
Mature milk is established within 2-3 weeks after delivery.

Types of Human Milk

Colostrum is thicker, higher in protein and minerals, lower in carbohydrates and fat than mature milk, which is thinner and more calorically dense.

Advantages of Breastfeeding for Infants

Nutritional benefits include ideal proportions of calories, carbohydrates (lactose), fats (triglycerides), and easier digestibility due to the whey-to-casein protein ratio.
Immunological components offer protection against infections and support intestinal health.

Advantages of Breastfeeding for Mothers

Enhances mother-infant bonding, reduces postpartum hemorrhage, and is economical.
Linked to lower risks of breast and ovarian cancers, osteoporosis, cardiovascular diseases, and diabetes.

Breastfeeding Management

Encourage skin-to-skin contact and deferring routine procedures to facilitate initial breastfeeding.
Monitor infant's weight gain (200 g/week expected), feeding frequency (8 times/day), and stool characteristics.

Contraindications for Breastfeeding

Maternal conditions such as active tuberculosis, varicella, herpes simplex, and HIV (in developed countries) may restrict breastfeeding.
Infant contraindications include galactosemia, phenylketonuria, and lactose intolerance.

Formula Feeding

Cow’s milk-based formula is commonly used, with iron supplementation recommended to prevent deficiency.
Soy-based and hypoallergenic formulas are available for infants with allergies.
Formula feeding is associated with higher obesity risk in childhood.

Comparison of Breast Milk and Formula Milk

Breast milk contains fewer proteins but higher levels of certain fats and enzymes such as lactoferrin and lipase, while formula milk includes fixed amounts of vitamin D but lacks certain protective components.

Weaning Process

Weaning, the introduction of solid foods, is typically initiated at 4-6 months.
Begin with cereals, followed by vegetables and carbohydrates like rice and bread, ensuring a gradual transition from milk-based nutrition.
