Well, my nephew is still wrapped in bubble pack. They actually wrap them in bubble pack in situations like this.
He has a subdural hematoma, which is a swelling in his brain. When they got him to the hospital, he was unconscious, then went into a coma. Then they put him under drug-induced coma so that he wouldn't wake up suddenly and jar himself. It is very important in these cases that they remain completely still, so that the swelling can go down.
In the next 24 hours they will learn more. They will be slowly taking him off the drugs and said that they may need to peel back the top of his head to relieve the swelling.
So basically, no good news yet, but no bad news either.
