My daughter was 6 weeks premature, and is now 6 weeks old. Today she is very restless, crying constantly. She is still feeding the same amount, but vomits some of it up. I noticed some green in the vomit. Her nose sounds a bit blocked, and i cleared her nose, pulling out green matter. Her tepmerature is normal. She has never been like this before, feeds and sleeps well. We feed her aptimal 120ml every 3-4 hours.
