His father shouldn’t have dropped him off there.
But if his mother wasn’t able to supervise him, he should’ve been with hospital security until police/ social services turned up. He should never have been allowed to be alone and hospital shouldn’t have allowed it. Enormous safeguarding failure for both patient and the 6 year old.
However I don’t believe the 6 year old is totally blameless….
My 5 year old would never pick up a baby without asking. She’d know they were real and poorly. And that’s without ever having visiting hospital. I can’t imagine any of her friends doing this in the guise of play. This is clearly a neglected / troubled child which isn’t his fault, but he did murder a baby. I think he really needs to be in a secure unit or care home with lots of therapy, and hopefully it’ll be the only horrific crime he commits.
Very sad situation.
