Start with
M
Your starting size in Traditional, Explorer and Abrazo, which all fit much the same way through the body.
Heavyweight, Striped and Melange fit like our standard flagship, so use the starting size above.
One little wooly disclaimer
We're pretty good at this, but we're not all-knowing. This is our best starting recommendation, not a guaranteed fit. Kids and adults come in different shapes, diapers vary enormously in bulk, and wool is a natural fibre. Fabric can vary slightly between colours and batches, and washing and shrinkage can affect the final fit.
Our recommendations combine what we know about our own patterns and fabrics with real fit experiences shared by Bumby families, to point you where we think you're most likely to land.
Covering a different diaper? Run it again. A trim daytime diaper and a heavily boosted nighttime diaper can give you completely different answers.
Lower cuffs that fit more like little bike shorts, with extra coverage through the legs.
Our most flexible cover, with an adjustable rise and waist tabs that grow with your baby for a custom fit at every stage.
Our most versatile wool layer. Use it as a booster, a night-time solution, or a lightweight cover over fitteds.
Wool joggers and harems in our heavyweight merino. Cloth diaper friendly and potty training friendly.
