Oct9 Jicama – 32 weeks Posted on October 9, 2012 by admin Jicama – 32 weeks You babies weigh as much as a jicama. Not sure what that is… picture looks like a potato. You each take up more and more space in my uterus and weighs as much as a large jicama — about 3 3/4 pounds. (Length: about 16 3/4 inches, head to heel.)
