What formula does this calculator use?

It uses the DRI (Dietary Reference Intakes) estimated energy requirement (EER) equation for ages 0–36 months published by the National Academy of Medicine: EER = 89 × weight(kg) − 100 + 20 kcal energy deposit. This age band has no physical-activity coefficient — that coefficient only enters the EER equations from age 3 onward.

Is this a replacement for a pediatrician's advice?

No. This tool provides a general estimate based on population averages. Every child grows differently. Always consult your pediatrician or a registered dietitian for personalized guidance.

Does sex affect this estimate?

No. The DRI equation used for ages 0–36 months is weight-based and does not have separate coefficients for male and female children.

Does activity level change the estimate?

No. The DRI EER equation for 0–36 months depends only on weight (plus a fixed energy deposit) and does not include an activity coefficient. Activity becomes a factor in the EER equations from age 3 onward.

My toddler eats less than the estimate — is that a problem?

Toddlers naturally regulate their intake day-to-day. As long as growth is on track and the pediatrician is not concerned, small deviations from the estimate are normal.

Does the calculator account for breastfeeding or formula?

No. The estimate covers total daily energy from all sources. If your toddler still receives breast milk or formula, count those calories as part of the daily total.
