Lilly & Frank Insert System – Clear Fit from Birth to Potty Learning

Our Lilly & Frank Inserts are thoughtfully designed to fit perfectly with our diaper shells, offering comfort and absorbency for your baby from newborn to potty learning. To ensure a great fit at every stage, we offer two insert sizes:

🌱 Stage 1 Insert – Infant (7–15 lbs)

• Snap-in snake style
  
• 6 layers of ultra-absorbent bamboo cotton fleece. Made from a blend of Oeko-Tex® Certified 70%bamboo+30% cotton.
  
• Designed to fit our diaper shells at the smallest snap rise setting—no bulky folding or awkward bunching.
  
• Once your baby outgrows the Stage 1 insert, you can reuse it as a booster inside the Stage 2 setup or pair it with another Stage 1 insert for extra absorbency.
  

Size Before Washing: Approx. 5.5 in x 22 in (14 cm x 56 cm)

Please expect approx. 10% shrinkage after washing.

🌿 Stage 2 Insert – Baby/Toddler (15–35 lbs)

• Snap-in book fold style
  
• 8 layers of bamboo cotton fleece for enhanced absorbency made from a blend of Oeko-Tex® Certified 70%bamboo+30% cotton.
  
• Wider, thicker, and longer to support your growing baby’s needs.
  
• Features a second insert snap on the diaper shell so you can easily add a Stage 1 insert as a booster—snap one in the front and one in the back to layer through the wet zone.
  

Size Before Washing: Approx. 14.56 in x 10.03 in (37 cm x 25.5 cm)

Please expect approx. 10% shrinkage after washing.
