Sizing

Choosing the right size for your baby involves more than just looking at the weight of your baby. Our guidelines are just that. Guidelines. It is important to note whether your baby is very slender or is very chubby. We also find that some babies may be able to skip a size.
If your baby is nearing the next size up and you are planning to make nighttime diapers, or use our covers over thick diapers, we recommend going to the next size up. Read more about our diaper fabrics on our Selecting Fabrics page.
