My wife and I read and internalize everything. These types of things get cataloged and we find ourselves living in fear and buying more newspapers making these people who peddle fear richer.
Truth is. None of us on this board as ever probably head of this, let alone know someone, let alone love someone that has happened to.
This poor family is devastated and it is a personal tragedy, yet regular drownings, electrocutions, and car accidents are far more deadly (and preventable). Our pediatrician always said to worry about water, fire, and electricity - not bumps or bumps in the night. She has 4 kids too so good advice.
I still snuggle every one of my kids to sleep every night I can (oldest is a soon to be 10 year old boy). In the end you can't stop yourself or them from dying and you have to look at the probabilities of things and protect the best you can - and then love them the best you can and pray about the rest.
