Hi, I have read your query carefully. I disagree with your guess. * Uterus is fixed in abdominal cavity by strong ligaments,muscles & other tissues and mostly uterine prolapse (slipping the uterus out) is caused by - weakening of the muscles/ligaments( child birth,old age, obesity) - increased abdominal pressure pushing uterus down( constipation, chronic cough, asthma, repeated/difficult child birth * Skipping is an exercise,which helps strenthennng of muscles& reduction of fat . Also you can observe while jumping up in skipping legs & lower abdominal muscles get tightened & strong . So please don t worry. an optimum number of skipping does no harm but is helpful for health, it is not likely to cause any problem in child birth. Thanks.
