That said, one thing to watch for: sometimes our perception of how much a child is eating doesn't match reality, or cultural expectations about weight can shift how we approach feeding. The research suggests it's worth checking in honestly with your pediatrician about whether his growth is actually lagging or whether his pattern might be normal for him.\n\nIf your pediatrician does confirm he's falling behind nutritionally despite good eating habits, oral nutritional supplements combined with feeding guidance can help him gain weight and strength more effectively than feeding advice alone. A pediatrician can determine whether supplements make sense for your son and help you figure out what's going on beneath the surface. Trust your instinct that something feels off, and let your pediatrician help you get a clear picture of what's actually happening.","sources":"[{\"pmid\":\"34684591\",\"title\":\"Oral Nutritional Supplementation Improves Growth in Children at Malnutrition Risk and with Picky Eating Behaviors.\",\"journal\":\"Nutrients\",\"year\":\"2021\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/34684591/\",\"score\":0.77},{\"pmid\":\"40779227\",\"title\":\"Parental weight perception and non-responsive feeding practices in Chinese preschoolers: a prospective longitudinal study.\",\"journal\":\"European journal of pediatrics\",\"year\":\"2025\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/40779227/\",\"score\":0.76}]","thread_json":null,"topic":"growth-and-weight","view_count":0,"created_at":"2026-08-25T02:32:57.698Z"}
