How it works
how our sizing works
As each baby is different and grows at its own pace. That's why our sizes range by length rather than age.
You can subscribe to the Björk Box from size 52-80, matching 0-18 months.
52-60 cm (fits 0-3 months)
62-68 cm (fits 3-6 months)
68-80 cm (fits 6-12 months)
80-86 cm (fits 12-18 months)
