Currently, you can only select one size per bundle -- but we hear you and are hoping to offer the option for multiple sizes soon.
In the meantime, if you're anticipating being in between sizes, we recommend sizing up since leaks and blowouts are far more common when diapers are too small. You can also purchase our Club Box individually if you want to try a size out before committing to a full bundle in a single size. We also accept returns on any unopened packs of diapers in case your little one happens to grow out of their current size.
If you need different sizes because you have two little ones in diapers, you can always have two separate bundles on a single account and adjust your frequencies based on each little one's needs!
