Arrggghhh...milk protein intolerance

CA2006

DD had green poops and trace amounts of blood at 5 weeks or so. She also had a hard time staying asleep. I eliminated dairy and didn't see a big difference. I have been slowly adding it back for the past 10 days or so and now DD has a cold and is really fussy (not like her). I thought it was the cold, but she has had a couple specs of blood in her diaper again   I am super frustrated.
