My 4 month old refuses a bottle

We started to introduce a bottle with breastmilk to my son when he was 3 months and we have been struggling for a month to get him to take one. We have tried the Avent natural, munchkin latch, Playtex and gerber bottles. He screams and cries everytime my husband and I try to offer him one. Any suggestions for other bottles or ideas that worked for you would help!
