My oldest son died very young (nothing criminal). My father wrote a eulogy for him and one of the final comments he wrote was how he (his only grandchild at the time) would not have to suffer in this world (he was healthy and had never suffered in his young life) and wouldn't endure heartbreak, sadness, etc like the rest of us. I didn't think anything of it - it was just an expression of pure grief and trying to find SOMETHING out of such a horrible tragic event. Of course my dad would have preferred my son lived and went on to have a normal life - with the unavoidable heartbreak, sadness, grief we all suffer.
So, I won't judge Coop's mom (I have a Cooper and assume Coop is this little guy's nickname as well). Unless you have suffered the loss of a child, you just can't fathom the things a person will say or think. Right now maybe she is thinking about the sweet glorious life of her angel in heave resting in Jesus' arms. Trust me, in a week, she will experience the physical pain of her arms not cuddling this child and mental anguish you can't imagine. In my experience, the flowery religious stuff only goes so far.
