A small infant’s head tilted back is an abnormal posture. It is possible that preterm infants live in neonatal intensive care for a longer period of time after birth, and some are intubated with tracheal tubes, which require maintaining a head-back posture and forming a habitual head-back posture after discharge from the hospital. Corrective methods are: hold the child when holding the head and then hold the body to prevent the head back posture (Figure 1); sleep, such as supine position, with a buckwheat pillow to fix the head and body in a straight position, side-lying position when the head behind a buckwheat pillow to prevent the head back; hold the milk bottle placed in a horizontal position or at an angle of 45 degrees to prevent tilting the head to eat milk (Figure 2). When holding the baby vertically, let the baby’s back rest on the mother’s chest, the mother’s one hand holding the baby’s chest, the other hand holding the baby’s buttocks, so that the baby’s head against the mother’s chest to prevent the baby’s head back (Figure 3). Usually, you can often do passive head forward bending exercises in the flat position. This can usually be corrected in about a month. If the head is severely tilted back, it may also be a symptom of brain injury and needs to be diagnosed by a doctor.
