My DD uses these diapers---she is very knowledgeable about them. All I have ever done is replace elastic or Velcro and made some bamboo liners. These babies ( 2 ) are allergic to most disposables and even the wipes. Found it is best to buy Velcro online--cheaper and stronger. You do have to be careful in buying the PUL--heard some were very bad. DD loves to use the wool diapers but so expensive.
