Miscarriage "Care package" for a friend

Kimber Kay

My best friend and his wife miscarried tonight, again 😔.

I gave them some kind words, along with my love and support. I know nothing about miscarriages, and I am looking for some insight on what to say to them about it. Also, is a miscarriage care package a thing? I'd like to do something sweet for them, but I also don't want to overstep and offend, or make things worse.
