A. A pocket diaper is a washable cloth diaper with a built-in "pocket" that holds the diaper's absorbent, center layer, often called a "soaker." The outside of the diaper is made of waterproof fabric, while the inside is usually made of fleece (or something similar), which stays soft against your baby's skin while wicking moisture into the soaker.
Parents can customize the center layer depending on their baby's elimination patterns and/or the time of day. For example, they can tuck a light soaker in the pocket during the day when they change their baby more frequently, and then put a heavier layer in for overnight. Like many contemporary cloth diapers, pocket diapers tend to come with rows of snaps or Velcro at the waist so you can adjust the size of the diaper as your baby grows.
Pocket diapers also come in a huge range of colors and patterns, but they don't come cheap, costing between $15 and $20 for solid colors, and between $25 and $30 for diapers with patterns or embroidery.
