- The WHO collects the main growth data of more than 8400 healthy breastfed infants infants and young children in 6 countries(Brazil, Ghana, India, Norway, Oman and USA).
- WHO standards are almost available for children aged 0-2 in all countries around the world.
- Australia can use the CDC standards, other countries can use WHO standards or nearby countries / nationalities as reference standards.
- These data are just statistical reference values. Each baby has its own growth path. As long as it is in a normal range, you don't need to worry about it
