It is valuable to have some extra boosters and inserts on hand. For All-in-two’s, you can buy extra sets so you can take out the soiled/wet boosting from the shell and replace with a new set. This means you dont have to buy as many whole nappies! Boosters are also handy to have if you need to leave a nappy on for an extended period of time (long car trip) or to add some extra protection for overnight. Boosters and inserts are available in Hemp, Bamboo or Microfiber.
