A Heart To Hold - This is a non-profit organization that was started by a mother that lost her son at 40 weeks. Another loss mama had made a heart for her that weighed the same amount as her Corbin did at birth. She now makes these for parents that have experienced loss for free--she only asks for donation.
Now I Lay Me Down to Sleep - Another non-profit that comes in and does remembrance photography for those parents that experienced loss. This is all done at no cost to the parents. The photos are take professionally, edited and are given to the parents to keep.
Faces of Loss, Faces of Hope - An online community to connect with other parents of loss, and to share and read stories. There are a lot of valuable resources from books, to blogs, to music to help you through the grief process.
Still Standing Magazine - An online magazine with some fantastic articles written by men and women that have experienced loss or infertility. I've found a lot of articles that I can relate to here. They also have a lot of other resources out there on their page. Love this group of people.
