Why does the second month baby cry?

There are two types of crying: physical crying, an instinctive response; the way babies express their emotions and needs, whether from hunger, cold, heat, shock or a dream, when parents can calm them down; and pathological crying, which requires attention. All causes of pain, itching and other discomfort diseases, will make the baby crying restlessness, such as fever, eczema, rickets, oral sore, pinworm infection, intussusception, etc. When the baby shows unexplained crying at night, parents should first start with physiological reasons. Then consider pathological factors, and when necessary, go to the hospital in time.
