I'm BF and I feel like baby is more fussy when I do. But I think that's my imagination. Coffee is amazing! I love it so especially after not having it for a day or two. It really gives me the boost I need.
I drink 1/2 caff coffee every day...about 4 cups. Have been doing it since by baby was 2 weeks and he's almost 11 weeks now. Hasn't affected my supply at all. I just make sure I drink plenty of water. Usually about 24 ounces after each feeding and a couple glasses in between feedings. I pump between 5-7 ounces (between both breasts) when I need to pump depending on time of day.
