This should be the first question right? So lets start from the begining! Lets go with Wikipedia: "A diaper (also called a nappy in South Africa, Ireland, United Kingdom, New Zealand and Australia) is a kind of underwear that allows one to defecate or urinate in a discreet manner."

A Baby Cloth Nappy, or Cloth Diaper is a piece of underwear made of fabric, that you can wash, like any clothes. It's a piece of fabric, that like panties will be next to your babies genitalia where your baby will pee and poo in. Traditionally since the 1800's cloth diapers consisted of a folded square or rectangle of linen, flannel which was fastened with safety pins. If you were born in the 70's and early 80's you were a Cloth Diaper Baby like I was. Today we refer this type of diapers (or nappies) as Flat Diapers or Muslins.

Modern Cloth Diapers are composed of layers of fabric such as cotton, hemp, bamboo or microfiber and can be washed and reused multiple times. To avoid leaks Cloth diapers can be impermeable such as Piriuki Mini, Piriuki Original, Piriuki Night, Piriuki Luxe, Piriuki Easy or need a Impermeable Cover like Piriuki Prefolds and Piriuki Cover.

Most Babies will need to use diapers for 2,5 years at least, and if your baby will need to change at least 8 times a day, so we're talking about more than 7000 diapers changes! Diapers are for sure the most important garment your baby will use for 24 during 2,5 years.
