For the knitters among you, here are some useful patterns for charity knitting to donate to NICU's for parents experiencing stillbirth or infant loss. I will never forget dashing down to the hospital gift shop to pay $25 for a little baby cap that was too big for Paul so that he would have a hat other than the generic hospital-issue one, something purchased especially for him. Parents who have received donated handmade items have been so grateful and cherish them always.
If you go to the pattern search on Ravelry and search for free knitting patterns with the word "preemie" in them, you will get 724 matches. Here are just a handful selected from the first page of search results, sorted by most-often knit first:
Berry Baby Hat by Random Stitches
Preemie Hats for Charity by Carissa Knits
Owlie Sleep Sack by Comfort Wool (This is not for sleeping in unattended. I think it would be useful as a burial bunting.)
