Prolactin, secreted by the anterior pituitary, is the primary hormone responsible for milk synthesis. Suckling stimulates prolactin release, ensuring ongoing milk production. Oxytocin is responsible for milk ejection (let-down reflex). Estrogen and progesterone prepare breast tissue during pregnancy but inhibit lactation until delivery.

Children with Type 1 diabetes typically receive insulin via subcutaneous injections (multiple daily injections, MDI) or insulin pumps (continuous subcutaneous insulin infusion). Oral insulin is not available as it is degraded in the gastrointestinal tract. Intravenous insulin is reserved for hospital settings (e.g., DKA). Transdermal patches are under research but not standard therapy. Insulin delivery must balance growth, activity, and dietary needs, making injections and pumps the mainstay in pediatric care.

The cornerstone of managing celiac disease in children is a lifelong strict gluten-free diet. Celiac disease is an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. Gluten exposure leads to villous atrophy in the small intestine, resulting in malabsorption, nutrient deficiencies, growth retardation, and gastrointestinal symptoms such as diarrhea, bloating, and abdominal pain. A gluten-free diet allows intestinal healing, resolution of symptoms, and normalization of growth and development in affected children. High-protein or low-fat diets are not specific treatments, and lactose intolerance may coexist but is not the primary concern. Families must be educated about hidden sources of gluten in processed foods, cross-contamination risks, and the importance of dietary adherence. With proper management, children with celiac disease can achieve normal growth and avoid long-term complications like osteoporosis and increased malignancy risk.

Skin-to-skin contact (kangaroo care) is the best way to prevent hypothermia in newborns. It provides warmth, stabilizes heart rate and breathing, and promotes breastfeeding. Immediate bathing and exposure increase heat loss, while feeding delays are harmful.

Head circumference is the primary anthropometric measure used to monitor brain growth in infants during the first two years of life. It reflects skull growth, which correlates closely with brain development. Normal patterns of head circumference growth indicate adequate neurological development, while deviations may signal conditions such as microcephaly, hydrocephalus, or malnutrition. Weight-for-age and length-for-age reflect overall growth status but are not specific indicators of neurological development. MUAC is primarily used to screen acute malnutrition in children over 6 months. Because the brain undergoes rapid growth in the first year of life, monitoring head circumference is a critical part of pediatric nutrition and healthcare assessments.
