Its important to pre-wash before first use. Wash diapers and inlays on a 40°-60°C program with prewash, spin speed 1200 rpm. Do not use fabric softener and do not tumble dry.
Prepare
1. Open the SUMO diaper and lay it flat so that the inside is facing up.
2. Take a UFO insert and slide it into the waterproof bag.
3. Place a Dreamliner sheet on top and tuck it into the pocket over the UFO insert.
Invest
1. Slide the SUMO under your baby's bottom and fold it up between their legs.
2. First close the snap fasteners and then tie the two ribbons into a bow.
3. Check that nothing protrudes and that there are no gaps between the leg elastics and the skin.
Here you will find detailed instructions with pictures.
How many cloth diapers do you need per day?
You'll need approximately 6-8 absorbent inserts per day. You should also have about 3 cloth diaper covers.
How many diapers you need in total depends entirely on your washing schedule. For a relaxed schedule (washing 3 times a week), we usually recommend 6 diaper covers and 14 inserts. You'll find this quantity in our Fulltime Set. The set contains enough diapers so you don't have to wash more often than every three days.
How long do SUMO cloth diapers last?
SUMOs are made to last and can be reused countless times. Once a child is potty trained, you can pass the SUMOs on.
Which size is right for my child? Our SUMO comes in three sizes. Size S is ideal for newborns up to approximately 5 kg. Size M fits children between 4 and 11 kg, and size L is ideal for children up to 19 kg.
Depending on your child's build, the different sizes will fit differently. The waistband can be individually adjusted using the ties and snaps on the diaper.
How do I wash the SUMO diaper?
We recommend washing the diapers and inserts on a 40-60°C cycle with pre-wash and a maximum spin speed of 1200 rpm. Please do not use fabric softener and air dry the diapers only.
How often do the diapers need to be washed?
The UFO absorbent insert should be washed after each use; the cover does not necessarily need to be washed as long as it is still dry.
We recommend washing all soiled diapers at least every two to three days.
What happens to the chair?
Our Dreamliner diaper liners collect your child's waste, making disposal easy. This means that feces NEVER end up in your washing machine, and with Dreamliner you have even less contact with your child's stool than with regular diapers.
What will happen to the Dreamliner?
With good flushing performance, you can simply flush our Dreamliner down the toilet. If you're unsure about your pipes or the performance of your sink, you can also simply dispose of it with your regular trash or wash it.
Cloth diapers in daycare. Does that work?
We recommend discussing this topic directly with the daycare center. However, with our Dreamliner and a wet bag, you'll make it considerably easier for the daycare staff to handle cloth diapers.
Can cloth diapers also be used at night?
Yes, you can. We recommend adding a muslin cloth as a booster to the diaper alongside the UFO to help keep the diaper as dry as possible.
Can SUMO cloth diapers also be used when traveling?
Although it may sound surprising, we are very often told that traveling with SUMOs is easier than traveling with disposable diapers, as diapers in other markets can function very differently or vary greatly in price.
However, it is important that you have regular access to a washing machine and do not leave your diapers unwashed for more than three days.
How absorbent is the SUMO diaper?
Our SUMO diaper is made with specially developed high-performance fabrics that offer ideal liquid distribution and absorbency. Depending on the child, our diapers are leak-proof for 4-6 hours. We recommend using a booster at night.
