All infants born, whether one day, or twenty-eight days newborn should not have their legs tied. Muscle tone should be observed from the child’s point of view, the infant’s muscle tone is greater in flexors than in extensors, the arms should be surrendered and the lower extremities frog-like, so that sleeping is very comfortable. If observed, children’s upper and lower limbs are much looser in flexion than adults, which is determined by the developing neurological brain, because the brain has not yet produced the inhibitory process that allows the extensor muscles to be larger than the flexor muscles. As the child’s brain develops, coordination will slowly emerge, so there is no need to tie the legs. Babies in the NICU wear only diapers and sleep comfortably in a humidity-controlled incubator at a constant temperature of 36 degrees. All babies are frog-shaped, with their hands up in a surrendered position and their feet bent to the sides. Never tie, after tying the child will have poor blood circulation in both lower legs and also very uncomfortable.
