A 3-year-old boy from rural Maharashtra is brought to the pediatric clinic by his mother. On anthropometry, his weight is 11 kg (10th percentile for age), height is 88 cm (5th percentile for age), and mid-upper arm circumference (MUAC) is 13.5 cm. His weight-for-height is 85% of expected. He has no clinical signs of edema or skin changes. Developmental milestones are normal. What is the most appropriate next step in management?
