In the 10th month of pregnancy, when it is time to give birth, I believe many expectant mothers will be a little worried, fearing that the delivery process will not go smoothly. In fact, natural childbirth can be a very simple matter as long as you master the correct method. A doula refers to a woman with childbirth experience who provides continuous physical support and assistance, as well as spiritual comfort and encouragement before, during and after childbirth. Not only are they experienced in giving birth, but they are also full of love, compassion and responsibility. Heart, and good interpersonal skills can give women a sense of security and dependence, so it is a good way to relieve labor pain and eliminate maternal tension.
