My little guy won’t take a bottle!!!

H E L P ! I’m going bonkers. My 3.5 month old will not take a bottle. When he was younger we tried some bottles (Dr. Brown’s) and he would take them but it took soooooo long to feed him that I just would nurse him. Now he pitches a fit when we (me or any another person) try to give him a bottle. I’m worn out and can’t nurse him for every meal anymore. Plus going out of town in Feb. without him and need him to be good with a bottle by then. Any ideas on how to get him happy with being bottle fed? Thank you!!!
