The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: The evil blood in a newborn is swallowed into the abdomen, causing distension and fullness in the heart and abdomen. The infant cannot suckle milk; this condition is called "Nanru" (Difficulty Suckling).
It also states: While in the womb, if the mother consumes cold foods, cold qi enters the uterus. After birth, the infant suffers from abdominal pain and refuses to suckle; this is also named "Nanru" (Difficulty Suckling).
