Auto Insurance Claims: Insurance negotiations, kids injury settlement

Question
Its been about 2 months since my son was hit by a car while riding his bike to school.  At this time the insurance has not officially said they are %100 fault.  There is no doubt in my mind that their driver was negligent.  My son was taking a right turn, she was coming from the opposit way taking a left turn onto the same street.  I have 2 eyewitnesses.  We took him to the hospital and they did a cat scan..everything turned out ok..however for the next 2 weeks my son complained about headaches.  His behvior seems more aggressive, very emotional.  He has had some memory loss.  I finally took him to see a neurologst to have them diagnose him and he did suffer a concussion.  This can be an on going situation and now he needs to rest.  At this point I need to contact the agent to tell him about the concussion.  Because of the head injury and the possibility of further visits how much should I expect or ask for.

Answer
I wouldn't expect over $2000.00, and that is if there is clear evidence of a concussion and the medical bills are at least $800.00.  If there is $350.00 in medicals and just the complaint of headaches, the treatment for a concussion is rest, so there isn't much in future medicals.  To get future medical settlements, you need a doctor to write down what is likely to be needed in the future and the associated costs.  Liability is always questionable when a bicycle and car have a wreck on an official roadway.  Both vehicles must abide by traffic laws, so it is a strike against the younger driver with less experience.
