As to CPR-- he let some random do it. And that's weird. I'm sorry. And getting on your phone is weird. I'm sorry. I am the biggest supporter of people who act weird after the death of a small child as I have witnessed one but, NO. I would not have someone else working my kid while I got on a phone. Maybe he was somewhat detached or maybe (eesh, I'm sorry) Cooper looked so bad he was squeamish. If I knew my son was dead, if I KNEW it, I would hold him and wait. I would not leave him on the pavement and function well enough to make phone calls. The only other option I would have would be to immediately off myself in the quickest way possible because I would be outta my head. Dialing my phone? Scrolling through contacts? NO.
I admit everyone is VERY different. My very dear, close friend was NUMB. Her eyes were glazed. So, this is just my opinion. I'd be stark raving lunatic. I was when he died. I lost myself repeatedly during the entire process of laying him to rest.
