It's best not to breast-feed like this, because incorrect posture may damage the child's internal organs. First of all, it's bad for the esophagus. When the milk position enters the doll, it is easy to choke the child, and the air is mixed, which is easy to cause abdominal pain, diarrhea and stomach pain, just like it is difficult for us to drink water when we are lying down. The best way is to let the child drink vertically and pat the child on the back to help him smooth. And I am used to lying down to feed, and my breasts can easily block the child's nose and mouth. If the child can't breathe, he may suffocate. Because when lying down, the child has to stretch his chin very hard in order to put the nipple in his mouth. When a child grows and develops, it will inevitably grow into a shoehorn face after a long time.
