DS (15) has been hit my a car near my youngest DC's school. I feel like such an awful mother for taking my eyes of him for even a second. I didn't leave him unattended for long, he was waiting outside DD's classroom whilst I spoke to her teacher as he didn't want to come inside I kept glancing up at him to check he was still there and when I glanced at him again he was gone. I had to appologize to DD's teacher and I rushed of to find him. I searched all around the area where he had been standing and then I rushed out to where other parents were standing and then I saw him. 
He was hit by a car going 20mph and is now in ICU after having a full blown seizure from a head injury. He arrived at hospital at 4pm and I've had to leave him and I feel so guilty. He's got a leg which is awful but I'm mostly worried about his poor leg. I feel so awful, what if the school contact SS and think I can't look after him properly. Do I need to hand DS to someone who can look after him properly as I clearly can't?
I feel awful for letting this happen.
