The Baby Growth Calculator estimates whether a baby’s weight is within a healthy range for their age and gender during the first year of life. It uses average growth standards derived from World Health Organization (WHO) data to compare your baby’s current weight to expected values for each month. By entering the baby’s age, gender, and current weight, you can quickly see if the growth is below, within, or above the healthy range. This tool helps parents and caregivers monitor early development and detect potential nutritional or health concerns. However, growth rates may vary individually, and medical advice from a pediatrician should always be sought for accurate assessments.
