CMPA help

I have been dairy free for about a week after seeing blood in my 9 week olds stool. As directed by his pedi. He isn’t a super fussy baby but definitely very gassy and uncomfortable when pooping. Also poops 50-10x/day and spitty. His stools have changed to a light green and much more seedy. Does this mean the diet is working? Also, does anyone eat baked milk? I accidentally ate a muffin with baked milk. Thanks!!!
