I am so sorry for your loss. Words get caught up in my throat — it’s small consolation, but you are not alone. Nothing will make sense for a while, this whole world won’t make sense. Help each other, but know that you will grieve differently than your wife. Luckily (is that a correct word?), there’s no wrong way to grieve.
I wish you both strength. I hope you can find a support group for neonatal loss, our hospital offered one at the time. And, again, please accept my condolences.
