Lilly & Frank All-In-Two Cloth Diaper Inserts

One absorbency system. From tiny newborn to potty learning.

The Lilly & Frank All-In-Two Insert System is designed to grow with your baby from approximately 7–35 lbs. Instead of replacing bulky inserts as your baby grows, our two-piece absorbency system adapts to changing needs while remaining simple, trim, and easy to use.

The system includes two purpose-built inserts:

Stage 1 Snake Insert

Designed for babies approximately 7–15 lbs, the Stage 1 Snake Insert provides a trim fit for younger babies without unnecessary bulk. Made from 3 layers of bamboo cotton fleece, its unique snake-style design folds to create 6 absorbent layers through the wet zone for excellent absorbency exactly where it's needed.

Stage 2 Book Fold Insert

As your baby grows, the Stage 2 Book Fold Insert becomes your everyday absorbency from approximately 15–35 lbs. The versatile book-fold design allows you to customize where absorbency is concentrated depending on your baby's needs while providing 8 absorbent layers of bamboo cotton fleece.

Designed to grow with your baby

Unlike traditional infant inserts that are quickly outgrown, the Stage 1 Snake Insert continues to be part of your diapering system.

Simply snap the Stage 1 Snake Insert into the second snap position on the Stage 2 Book Fold Insert to create 14 absorbent layers, making the perfect combination for naps, overnight, or heavier wetters.

One insert doesn't replace the other—they work together as your baby's needs change.
