Pregnancy Profile Vest simulates the experience of being nine-months pregnant. The RealCare Pregnancy Profile replicates many of the physical effects of pregnancy, including 25-30 pound weight gain, raised body temperature, bladder pressure, fetal kicking and so much more. Combine with its accompanied curriculum, students will learn and discuss the physical, emotional and social impacts of pregnancy. This vest is a one-size-fits-most with adjustable straps. This is a great, experiential learning tool for prenatal classes, child development education and general health courses.
