Please refer "SIZE" at Green BeBe Contents.Sizing tends to run small so you may want to go to the next size especially if your baby is at the middle or end of a weight range.
Please try out a cover before washing them to ensure proper fit. With a diaper cover, size is very important. Be sure that the cover is snug around the legs and waist. Check the diaper to ensure that all cotton is tucked inside the covers. This will keep the diaper from wicking the wetness to babies clothing and the diaper cover.
Staining on the inside of diaper covers is normal and should not cause any alarm, especially when the baby is eating solid foods or if the baby is taking any medication. If you have stains that you would like to address, pre-soak with a washing detergent specially for stains prior to the wash process. Hanging the covers in the sun for a few hours may help to reduce the appearance of some stains. Remember that any chemical that you add to the covers will affect the longevity of the diaper covers and the effectiveness of the waterproof layer of the covers.
Wash the covers in cold water. The covers can be washed with other clothing on the shortest washing duration possible. It is best to close the Velcro and turn the covers inside out to ensure the best cleaning possible.
