11 weeks old rejecting bottle

Hi Mummies, My 11 weeks old boy has suddenly started hating bottles. I have used MAM bottle since about 3 weeks, but now he is just straight up refusing, even when I know he is hungry. He would latch instead. From 3 weeks onwards it has been a mix of bottle feed and latch but now he is not taking bottle at all :( I love that mom is comfort, but I go back to work in 3 weeks and am wanting a smooth transition! What do I do? Any tips. I am really worried #firsttimemom #firstbaby
