We were talking about preemie charity projects in chat earlier. This is one of the other sites I have in my favorites. (The site does state that these patterns are for personal / charity usage only)
There are a few that I have not looked at, just because the thought is so sad. I can, however, see where they would be a comfort to bereaved parents.
Scroll down just a little and you'll find the fleece preemie cuddler we were talking about.
There are tons of projects on this site, for all kinds of needs. Including projects for chemo patients.
