I forgot my two year old son was in the back seat once. I just popped in to a store for 2 minutes and was parked right next to the front door. It wasn't hot or anything, but I still felt like the stupidest guy on earth after the incident.
I can't even imagine how this guy must feel. If it were me, I'd probably need suicide watch.
My son, always woke up and started crying the minute the car stopped. Built in alarm I guess. I just can't see forgetting the little ones in the car.
