Dairy/Soy

Poor baby is still having diharrea/mucus and an occasional speck of blood after I've eliminated dairy and soy.  My husband just realized the cooking spray he uses for our eggs has soy in it...could something that small do it?  Or is it time to try the next elimination?  Been to the doctor plenty and they seem to use the same guessing method I would.  Plus her 4 month check up is in a few days.
