Newborn babies do not need to tie their legs. If the baby is tied after birth, it will make the baby fixed in a posture, so that the baby’s muscles are in a state of tension, which is not conducive to the growth and development of newborn babies, and it will also limit the activities of the hip joints, affecting the development of the hip joints. After the birth of a newborn baby should let the baby wear comfortable loose clothes, let it grow naturally, in order to facilitate the growth and development of muscles and various systems. In addition, parents should be patient and careful when taking care of their newborns and breastfeed as much as possible. It is important to keep an eye on your baby’s development and have a good physical examination.
