The correct posture for holding a baby

The correct posture of holding a baby should be determined according to the baby's age. Choose a baby before half a year old. When holding the baby, try to hold it horizontally, and use your arm to hold the baby's back. You can't always let the baby rest on your arm, but should let the arm and the baby's back be in the same straight line. After holding the baby for half a year, you can choose to gradually hold it vertically. However, when holding the baby upright, you should hold the baby's back to prevent the baby from tilting his head backward.
