Daily caloric intake by age
| Age | kcal/kg/day | Notes |
|---|---|---|
| 0–3 months | 100–120 | Breast milk or formula only. Feeding every 2–3 hours. |
| 3–6 months | 90–100 | Breast milk or formula remains primary nutrition source. |

How the math works
1
Get your baby's weight in kg. If you have it in pounds, divide by 2.2.
2
Multiply by the kcal/kg/day rate for your baby's age range (e.g., 120 for 0–3 months).
3
Divide across feedings to see how much your baby needs per session.
