H.S.
The best thing I got from friends when I lost my two was hand written notes & cards. That way I didn't have to talk to them about it but it gave them a way to let me know they were thinking of me. I don't know if they have other children already but offering to take the other kids is also a great way to give them time to grieve without worrying about what their other children will think or having to be a parent while grieving.
