16 snaps ensure that you can find the best fit for any baby. Fold down the front to fit a newborn and leave up to fit a toddler up to 35 lbs! Buying a one-size diaper is more cost effective (24 diapers vs. 24 diapers in 3 sizes=72!). Since hemp is more absorbent than cotton, the 3 layers are significantly less bulky than a cotton diaper of similar absorbency. Every baby will appreciate that! These are not waterproof and do require a cover. Handmade in Maine, USA. Why hemp? Our 55% hemp/45% organic cotton fleece diapers are very soft for a hemp product. Hemp has long fibers, which mean longer garment life and more absorbency. Hemp is 4-8 times more absorbent than cotton and has natural anti-bacterial properties! It is wonderful for babies with sensitive skin. This package contains 12 Boo Bear Buns one size fitted hemp/organic cotton fleece diapers, 6 inserts/doublers and 12 plain wipes. Absorbency refers to the soaker layers 1 is 1 layer, 2 is 2 layers and 3 is for 3 layers. Launder 3-5 times before use to wash away the natural oils in the material. A biodegradable detergent will be gentler to the fabric and baby. The more they are washed, the more absorbent they get!
