If you listen to the 911 call...you can tell the operator is surprised when mom said a 2 year old has been gone an hour. She sounded like, "An HOUR??" We have to take it on the basis of the 911...not what grandad said, not what dad said...the MOTHER stated he has been missing an HOUR. It's useless to try to do all these timelines with everyone having a different story. I would think the Mom out of everyone would know how long her 2 year old has been missing.
