I've discovered why Nola is considered "small."
Different growth chart! The WHO (not the band) has an international growth chart which is based on weights and lengths of babies who are breastfed exclusively for at least 4 months and at least partially until 12 months with no solids until 6 months.
And by those numbers she's exactly average for weight and a little above average for length.
Check them out here for girls and here for boys.
