S.,
I can't help you with the DCF issue. I do recommend a lawyer. Don't be hard on the medical staff. They are required by law to report anything supicious. If you read the papers & what people do, it hardens them. People to awful things to other people, kids & animals- some strange reasons.
As far as the bleeding- is he cutting teeth?. Did they scope his nasal passages? Even though he vomited- irritation from sinuses- not causing a nose bleed, could show up in the vomit.
Good luck
