It is more common for women pregnant with multiples to wrap their stomachs because they grow so quickly. With the increased growth comes discomforts such as extreme itching from the stretching skin. They wrap it with saran wrap to avoid getting medicine on clothes or bedding. I remember seeing Kate Gosselin doing this, but couldn't find a video. Here is a website I found though. http://ift.tt/1n35xyS's_belly_wrapped_in_saran_wrap_while_in_the_hospital_pregnant_with_the_sextuplets
