一般来说，专业月嫂应该掌握和熟悉科学卫生育儿的基本技能和相关的服务程序。比如：婴儿游泳、按摩、沐浴、喂养、护理、早教等方法，为产妇提供孕产期保健饮食、生活及生理护理、乳房与伤口护理、形体恢复和产褥卫生等。而有些家政公司或中介公司提供的价格便宜的月嫂，其实只是名义上的月嫂，实际上只是普通保姆。由于月嫂提供的服务更加专业，所以其服务价格是不会跟保姆的价格一样的。
Generally speaking, professional Yuesao should master and be familiar with the basic skills and related service procedures of scientific and health care. For example: infant swimming, massage, bathing, feeding, nursing, early education and other methods to provide pregnant women with healthy diet, life and physiological care, breast and wound care, body recovery and puerperal health. And some housekeeping companies or intermediary companies provide cheap Yuesao, in fact, only in name of Yuesao, in fact, just ordinary nanny. As Yuesao's service is more professional, the service price will not be the same as that of nanny.
