Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to wear a diaper as an adult [title] Fold the diaper properly. [step] Before you put on your own diaper, make sure to fold it properly. Fold the diaper length-ways with the back sheet facing outwards; you don't want a hard crease, just a soft fold.

Ending1: Make sure you do not touch the inside of the diaper. You do not want to contaminate it. Ending2: The diaper should be snug, but not so tight that a baby has to squirm his way out of it. Holding it over your head is particularly important, as it will keep you from getting dirty. Ending3: This will prevent redness or wrinkling. [substeps] Fold your diaper about 20 centimeters. Ending4: Be sure to leave a little extra so the diaper strip can be snug on your baby's rear. [substeps] You may find that the extra height makes it easiest to put the diaper on your baby.
