In olden days, that is to say, 1972, disposable diapers started being made with adhesive tapes. Not resealable tapes. Just tapes. My mother had been using safety pins with disposable diapers for more than 3 years, with 2 children, and countless diapers. She recognized that the tapes were a great advance, with no risk of sticking the baby with the pin, no problems finding the pin when you needed it.

But she had a terrible time with the tapes. She would get one side stuck, and if it was too tight (because it seemed like my little brother had grown overnight), she couldn't just adjust it the way she did with pins. Sometimes my brother batted at the diaper when she was trying to line it up, and got it stuck in the wrong place. It was infuriating.

So she went back to using safety pins. Just because the diapers come with tapes doesn't require you to use them. (Your hand goes between the diaper and the baby when you're fastening the pin.)
