If you give the newborn improperly put the stool, put urine, will cause the following harm: first, cause the newborn to delay the establishment of urinary reflex, because the newborn’s age is relatively small, the development of the brain nervous system is immature, especially the conditioned reflex of the urinary center is immature. If the parents give the newborn too early to put the stool, put urine, will interfere with the newborn’s normal urinary reflex establishment. Secondly, it will cause hip dysplasia of the newborn, because the age is relatively small, the hip joint is not mature, and the ligaments around the hip joint are not too firm, so it will cause hip joint injury of the newborn after putting stool and urine too early. Therefore, parents should not give the newborn baby to put the stool, put the urine, when the age increases after the urinary reflex will naturally be established.
