Thanks to all of u. I remember vaguely that in the movie "meet the parents", the grandpa was wearing a breast-like bag to feed the baby. I wonder is there anything like this for sale? If there is, what's the name? My friend who is absolutely worried about this problem with her baby wants it badly. I have told her repeatedly to relax and the baby will have to accept the bottle if she's really hungry. But the mother insisted that her baby had just gained the weight of about 500 grams in the third month and she's afraid the baby might suffer from malnutrition. It's really tough to get it solved. Thanks again!
