My twins, I think because there are two of them, decided to take their clothes off every night. Once I put them to bed, they would strip down. I didn't know it until about 3:00 in the morning when one of then would wake up crying, the bed wet, both naked; I didn't know what to do. I would tape it, they would figure that out. I would do the draw string, they figured out how to untie it. I didn't know what to do. It was driving me crazy. I, ultimately, got some of those zipper pajamas, cut the feet out, and flipped it around. They got it. They were really mad. They were old enough that they didn't like it, but that solved it. They quit taking off their clothes.
