For newborns and babies up to 15 lbs, we have the "mini" version of our One Size Deluxe. It is made with a waterproof outer layer of PUL and an inner layer of microfleece. It comes with a bamboo insert. Its unique snap settings gives you 3 different sizes and allows you to adjust the size for a newborn and babies up to 15 lbs. Before using the diapers: wash and dry your diaper once in hot or warm water prior to first use. This causes the fibers to shrink, fluff up and become more absorbent. It is not necessary to wash more than once before using the diaper for the first time. The inserts will shrink and get thicker with the first few washes. This shrinkage has been allowed for when designing the inserts. General Wash & Care: Keep your wet and dirty diapers in a diaper pail. If you've stuffed the inserts inside the diaper, shake out the insert into your pail and throw the diaper in after changing your baby. Wash your diapers in hot or warm water on regular cycle. Follow the recommended amount of detergent as stated on the soap's packaging based on your load size. Too much will leave residue causing your diapers to possibly stink, leak, or leave baby with a rash. Too little will not leave your diapers clean and cause it to stink and/or leave baby with a rash. An additional rinse can be used for particularly soiled loads. Make sure that your diapers are rinsed clean. Any residue from poop, urine, or detergent can make your diapers smell. Tumble dry on any temperature or line dry. Do not use fabric softener. It will coat the diapers making them water repellent and reduce the absorbency of the diaper. Be aware that if you use dryer sheets in your dryer for other laundry this can coat your dryer and transfer to your diapers. Do not use bleach. This will cause the fabric's fibers to break down. It will also cause the waterproof layer of the diaper to de-laminate. Do not use baking soda or vinegar in your wash.
