Gassy baby

My son is 5 weeks old and he cries every time I try to feed him, I am exclusively pumping and bottle feeding him, I try not to eat or drink to much dairy or any foods that would make him gassy, he will such a few times on his bottle and then scream in pain, I use Kolick to help but it doesn't help quick enough, I do bicycles and he just cries in pain even after he poops, is there anything else I can do?
