Colic is a condition that causes unexplained and prolonged crying in infants. If a baby is colicky, it is a good idea to swaddle a baby tightly to make it feel like it is back in the comfort and safety of the womb. Using things like a hair dryer or a fan can imitate the loud sound of blood flowing through a pregnant woman’s arteries. It is a good idea to keep the baby in movement, such as rocking or riding in a car, that reminds them of the womb. The baby can feel soothed with warm baths and warm wash cloths placed on their stomachs. By the time a baby is 3 or 4months old, colic symptoms usually go away and don’t return.
