The dark side being Velcro. I like snaps and so does my family in theory, but I keep finding snap fitteds on the baby backwards, on the wrong setting or hanging on by one snap, courtesy of my mother or my husband. The Velcro fitteds they get right, no problem. I remember DD1 went through a phase where she would remove Velcro but not snaps, but it was a relatively short-lived phase....
