When feeding formula, you can pick up and feed and lie down. If you pick up and feed, make the baby’s head and body in a straight line, with the baby’s body close to the mother and the head and neck receiving some support. If feeding lying down, keep the baby in a side-lying position and put as much of the pacifier into the mouth as possible when its mouth is wide open so that it does not suck completely and correctly. When feeding formula, make sure the baby is given in a hungry, awake, warm and clean state. When breastfeeding, pay attention to the fact that after the formula is heated, you can drop the formula on the inside of your wrist so that it does not burn your hands, and the breastfeeding time is about 10-20 minutes between. After breastfeeding, the baby should be held straight, with the head resting on the mother’s shoulder and patting the back to get out the air swallowed in the stomach while breastfeeding, so as not to cause overflow and abdominal discomfort.
