Infantilism, Feedism, Paraphilia, Pediatric Obesity, Adiposity Rebound, Weight Gain Game 1. Introduction The phrase “baby fat” typically refers to the subcutaneous adipose tissue present in infants and toddlers, which normally diminishes during early childhood (ages 2–6) before a healthy “adiposity rebound” around age 5–7. The addition of “weight gain game” suggests a structured, goal-oriented activity. However, no legitimate health organization endorses intentional weight gain in children beyond medical refeeding protocols.
