Baby Calorie Needs Calculator
Calculate your baby's daily calorie requirements based on age, weight, and activity level for healthy growth.
How It Works
Enter your baby's weight and age. The calculator applies WHO/DRI caloric density recommendations: 108 kcal/kg/day for 0-6 month olds and 98 kcal/kg/day for 7-12 month olds, then provides practical feeding equivalents.
Formula
Daily Calories = 108 kcal/kg (0–6 months) | 98 kcal/kg (7–12 months)
