Keep in mind that “desirable” weights fall within a range. Also, understand that there are special circumstances where some women will need to gain more, some less. For instance, women carrying twins will need to gain about 35– 45 pounds, and although women with triplets almost never carry full term (they typically deliver around 33 weeks), if they did, they would need to gain in the vicinity of 50–70 pounds—and hire three full-time nannies and a massage therapist. Rap with your doctor and listen to his or her advice on this weighty issue.
