Article in English: Resting on all fours will help the baby into a good position. When the baby’s head puts downward pressure on your cervix, the cervix starts to efface, or shortens and thins out. Resting on all fours for 10 minutes at a time, several times a day, can help move the baby’s head into the optimal position. You are probably exhausted at this late stage of pregnancy and ready to just relax. But reclining or sitting back on the couch can be counterproductive to making sure the baby is in the right position for labor. Instead, lay on the couch on your left side, slightly rolled forward. Prop yourself up with cushions to make it comfortable. A birth ball is a large bouncy ball (they are also used in exercising) that can help you sit comfortably towards the end of pregnancy. You can also use this ball to help you cope with labor. Sitting or bouncing on the ball, while spreading your legs wide, can help the baby move downward.

Summary in Chinese:
