Meet Lava - A colorful and adorable Newborn cloth diaper cover brought to Kanga Care in 2017. The Rumparooz Newborn Cloth Diaper Cover is designed to grow with your baby with 3 adjustable rise settings that are designed to fit your preemie and newborn. Weight range of cover starts at 4 pounds and will fit up to approximately 15 pounds. Rumparooz Newborn Cloth Diaper Covers are generously sized and designed to fit over most newborn fitted or prefold diapers. Covers may be used multiple times before washing but should be placed into the laundry if it becomes soiled. Kanga Care uses a water resistant polyester TPU which is a solvent-free polyester fabric that has been laminated with a thermoplastic polyurethane using a heat bonding process, not chemicals. This process is low in toxicity and is better for the natural environment then traditional PUL.
Newborn / Preemie Cover = 3 Sizes in One!
The Rumparooz Newborn / Preemie Diaper Covers have 3 adjustable rise settings that are designed to fit your tiny baby averaging 4 to 15 lbs with 1 cover.
Additional Information

- Before first use, wash diapers once.

Three adjustable rise settings let one cover fit babies from about 4 to 15 pounds, so you can use the same cover as baby grows. Snap the rise to the right setting and fasten over a flat, prefold, or newborn fitted diaper for a snug, leak-resistant fit.

Kanga Care uses a polyester TPU that is laminated with thermoplastic polyurethane using a heat bonding process, not harsh solvents. That means a water resistant interior with lower toxicity and a smaller environmental footprint than traditional methods.

Rumparooz Newborn covers are generously sized to go over most newborn prefolds and fitted diapers, so you can build a simple, economical diapering system. Covers can be used more than once between changes if they are not soiled, and should be washed if messy.
Pick the cover that matches your baby, washing habits, and diapering style.
- Start with weight: Use your newborns current weight, not age, to pick a cover that will fit at the smallest rise setting.
- Pair with prefolds: Covers work best over a flat, prefold, or newborn fitted diaper for absorbency and a trim profile.
- Consider laundry habits: If you do laundry less often, plan for extra covers and inserts to keep on rotation.
- Look for secure fit: Elastic leg gussets and adjustable rise snaps reduce leaks and keep baby comfortable.
- Care and longevity: Wash covers once before first use and avoid laundry additives like bleach or borax to protect the TPU.
Will this fit my preemie?
Yes, the newborn cover snaps to the smallest rise setting and is designed to fit from about 4 pounds, so it will work for many preemie and very small newborn sizes.
Can I use the cover more than once between washes?
Yes, covers may be used multiple times before washing as long as they are not soiled, but place the cover into the laundry immediately if it becomes messy.
How do I wash and care for these covers?
Wash once before first use. Routine care is a cold rinse, a hot wash with recommended detergent, a cool rinse, then tumble low or air dry in indirect sun.
Will this cover fit over my prefolds and newborn fitteds?
Yes, Rumparooz newborn covers are generously sized to fit over most newborn prefolds and fitted diapers for a secure system.
What are your shipping and return policies?
We ship from a US warehouse and offer free US shipping on orders over $100. We accept returns within 30 days and provide human customer support if you need help.
