Limited maternal knowledge of infant and young child feeding (IYCF) practices contributes to inadequate dietary intake and poor nutritional status among children under two years old. Emotional-Demonstration (Emo-Demo), an educational approach that combines practical demonstrations with emotional engagement, has shown promise in improving feeding behaviors. This study aimed to assess the effect of IYCF education using the Emo-Demo method on children’s energy intake and nutritional status. A quasi-experimental study with a one-group pretest–posttest design was conducted at the East Purwokerto I Health Center between May and August 2024. The intervention consisted of seven educational sessions. Energy intake was measured using a single 24-hour food recall, and nutritional status was assessed using weight-for-age z-scores (WAZ) obtained with a digital baby scale. A total of 18 mothers of children under two were recruited using purposive sampling. Paired t-tests were used for data analysis. Most mothers were aged 20–35 years (77.8%) and were housewives. The Emo-Demo intervention significantly increased mean energy intake (+239.6 ± 239.9 kcal/day, p<0.001, d=0.72) and improved WAZ scores (+0.23 ± 0.27, p=0.002, d=0.23), indicating positive effects on both dietary intake and nutritional status.
