American baby sizes are based on the age, but since babies may vary a lot in size, it’s better to focus the size on the baby’s weight and height.
For toddlers and small kids, use the first size chart which is for both girls and boys. For older children, use the respective chart for girls and boys.
Please note that these size charts are just a guide to your child’s clothing size, and that the sizes may vary between different brands.
