I am so very, very, very sorry for your loss.

Andrew
Thank you for the courage it took to share your story.
I hope you find the answers you need. I wish I had some answers to offer.
From your phrasing, I assume you know about
this site about Sudden Unexplained Child Death, but thought I'd mention it anyway, just in case. The site mentions peer support services for family members, and childcare providers, too, who have experienced this kind of loss. Maybe connecting with others in similar circumstances might help with the search for answers?
In a similar tragedy in my own community a couple of years ago, the bereaved family found meaning in raising awareness about SUCD and funds for research into causes.
The Compassionate Friends is an organization that I have some personal experience with, one that has helped people I know well who have experienced the loss of a child.
My prayers and condolences to you and your family, and to the little boy's family. What an unspeakably devastating experience for all of you. May you find peace and healing.
