Frequently Asked Questions
Is average monthly gain the same as a growth percentile?
No — this calculates a simple average, not an official percentile. For accurate growth percentile tracking, your pediatrician plots actual measurements against WHO or CDC growth charts, which account for age and gender-specific patterns.
What is typical weight gain in the first year?
Babies typically gain weight fastest in the first few months (often 150-200g/week initially), with the rate gradually slowing — by 12 months, many babies have roughly tripled their birth weight, though individual variation is normal.
When should I be concerned about my baby's weight gain?
Always discuss any weight concerns directly with your pediatrician, who can assess actual percentile trends and overall health context rather than relying on a single average gain figure.
