Recommendations
Based on your baby’s growth percentiles, we recommend maintaining current nutrition and monitoring growth at regular intervals. Always consult with your pediatrician about any concerns.
Frequently Asked Questions
WHO standards are based on healthy breastfed infants from diverse ethnic backgrounds, while CDC standards are based on a broader population of US children including formula-fed infants.
For infants (0-12 months), monthly measurements are recommended. For toddlers (1-3 years), every 2-3 months is sufficient unless otherwise advised by your pediatrician.
Percentiles show how your baby compares to others of the same age and gender. Higher percentiles mean larger measurements, lower means smaller. What’s most important is consistent growth along a percentile curve over time.
Consult your pediatrician if your baby crosses two major percentile lines (e.g., from 75th to 25th) or if measurements are below the 5th or above the 95th percentile consistently.
