My 9 month old has been crying and moaning for 4 hours. He passed a large amount of large hard cylindrical stool 3 hours ago. He has a low grade fever 101.7. He is refusing formula -- he has had 14 oz today, but normally would have had 22 by now. He has been sick a lot this winter -- repeated bronchiolitis, strep, croup, norovirus, but has NEVER been this upset. He's unable to nap even in my arms.
