This is the perfect trainer for even a young toddler! Organic cotton inner, snap-in insert and PUL in the wet zone make this a one-of-a-kind option for your child. This trainer is meant to be a learning tool for your child and is not 100% waterproof. This trainer is meant to catch a single accident and then be changed. As your child becomes more independent you can take the insert out for a trimmer option. If there is only a small accident, the insert may be replaced and the rest of the pant reused. Material Contents Inner: 100% Organic Cotton, Outer: 50% Certified Organic Cotton and 50% Polyester Care Instructions Prep diaper before first use by washing 6-8 times. Test the absorbency by pouring water onto the dry diaper; it should absorb instantly. If it does not, wash a couple more times and try again. The number of washes required to properly prep the diaper depends on the type of washer and detergent, as well as the hardness of the water. Wash and dry warm. Do not use bleach or fabric softener. Features Available in 2T, 3T and 4-5T. Gentle elastic around the waist and legs allows for easy up and down. Each trainer includes six layers of organic cotton absorbency. Hidden waterproof layer in the wet zone.
