Assuming you are talking about a diaper changing station for a baby, you will need the following items:
-A changing pad. This is a padded mat that goes on top of the dresser or table where you will be changing your baby's diapers. It should have raised sides to keep your baby from rolling off.
-Diapers. You will obviously need diapers for your baby to wear! Stock up on whatever size and brand you prefer.
-Wipes. Baby wipes are essential for cleaning up after a dirty diaper. They are usually sold in large packs at most stores.
-A trash can. This is for disposing of soiled diapers after you've changed your baby's diaper. Place it close to the changing area so it's easy to grab when needed.
-Diaper rash cream or ointment (optional). If your baby gets rashes often, it might be helpful to keep some cream or ointment on hand to treat them quickly.
