Check a baby's weekly weight gain against typical ranges.
Weight velocity measures grams gained per week between two weigh-ins and compares it with typical ranges for the baby's age. Remaining within the band is the reassurance pediatricians look for at well visits. Weight gain is the earliest, most sensitive marker of infant health, so a simple at-home velocity check tells parents when to mention concerns to their doctor.
Baby Weight Gain Check
g/week = weight gained / weeks, compared with typical bands (150-200 g for 0-3 mo, 100-150 for 3-6, 60-90 for 6-12, 30-40 for 1-2 y)
For guidance only; pediatricians interpret growth in context of the whole chart.
