Kangaroo mother care (KMC) involves skin-to-skin contact between mother (or caregiver) and preterm/low-birth-weight infants. It improves thermal regulation, promotes breastfeeding, enhances bonding, reduces infections, and improves survival rates. KMC is particularly beneficial in resource-limited settings where incubators are scarce. Unlike formula feeding or incubators, KMC provides physiologic and psychological benefits simultaneously, supporting both nutrition and development.

Carbohydrate counting is a method where insulin doses are adjusted based on the amount of carbohydrates consumed. It allows flexibility in food choices while maintaining good glycemic control. Protein and fat intake are important for overall nutrition but do not directly determine insulin dosing. Avoiding all carbs is not recommended, and fixed insulin doses increase the risk of poor control.

Children with celiac disease must avoid all foods containing gluten, which is found in wheat, barley, and rye. Gluten ingestion triggers autoimmune-mediated damage to the small intestinal villi, causing malabsorption and complications like anemia, growth failure, and osteoporosis. Rice, potatoes, corn, millet, and quinoa are naturally gluten-free and safe alternatives. Education on hidden gluten in processed foods is essential for long-term disease management.

Bitot’s spots, foamy lesions on the conjunctiva, are caused by vitamin A deficiency. They are an early sign of xerophthalmia, which can progress to corneal ulceration and blindness if untreated. Vitamin D deficiency causes rickets, vitamin C deficiency causes scurvy, and vitamin K deficiency leads to bleeding disorders. Vitamin A supplementation programs have been key in preventing blindness in children worldwide.

Long-term TPN can cause liver dysfunction, including cholestasis, steatosis, and liver fibrosis. Monitoring liver enzymes and bilirubin levels is essential to detect complications early. Renal function should also be observed, but the liver is most affected due to metabolism of lipids and glucose in TPN. Cardiac and pancreatic complications are rare in PN compared to hepatic issues.
