I don't have kids of my own but my SO's sister has twin boys, aged 5 months. Reading this article was tough. What if one of her sons doesn't wake up one day? What if something happens to both of them? She and her husband have busy careers, and while I won't share this article with them (it'll probably be a sore spot) I'm hoping that they'll make enough time for their kids.
