How to Choose a Cloth Diaper Cover

Pick a cover that matches your diapering system, your laundry routine, and your baby’s size changes.

  1. Think about your system: Decide if you will use fitteds, prefolds, pockets, or all-in-ones, then choose covers that work well with that system.
  2. Size and adjustability: Look for rise snaps and leg elastics so one cover can fit through several size stages, reducing how many you need.
  3. Material matters: Water resistant TPU covers are durable and easier to care for than untreated fabrics; ask how the lamination is made if you prefer lower-toxicity options.
  4. Laundry reality: Plan a routine you will actually keep, and remember covers can sometimes be reused between changes unless soiled.
  5. How many to start: Start with a small rotation so you can test fit and wash habits, then add covers based on how often you want to do laundry.
