Problem: Jackson Rivera is a 14-month-old boy brought to the pediatric clinic by his mother, who is concerned about his poor weight gain and lack of appetite. Jackson was born at 38 weeks via normal vaginal delivery, with a birth weight of 2.9 kg (6.4 lbs). He was breastfed exclusively for the first six months, after which his mother introduced solid foods, but Jackson has been a picky eater, often refusing food and taking only small amounts. Jackson lives with his mother, father, and two older siblings in a small apartment. His mother stays at home to care for the children, while his father works long hours. The family has limited access to nutritious foods due to financial constraints, and Jackson's diet primarily consists of formula, occasional pureed foods, and snacks like crackers and juice. His mother reports that Jackson is often irritable, has frequent loose stools, and is not as active as other children his age. Need Online Tutoring?
