I, too, never received any support from the March of Dimes while my son was in the NICU for three months in 2011. I didn't learn about them until later. I think it depends on the hospital, but I'm not sure about that. I have since learned a lot more about them and now I know that a lot of what saved my son came from research funded by the MoD, and I know they advocate politically. But, hearing about "support specialists" from other families made me wonder why we didn't have that. I don't want to complain because the staff at the hospital was AMAZING and cared for us along with Sam. But still, it didn't seem like it should be a highly-trained nurse's job to arrange for us (not their actual patients) to get meals and housing. I don't know if that has changed in the years since. I read about MoD support specialists providing activity areas for siblings, working with the Ronald McDonald House, holding scrapbooking sessions for moms and families, helping with insurance paperwork, and things like that. All of that kind of stuff was done, at my hospital, by the staff, usually RN's. They were fabulous and caring people and it made it so much easier for us to have them, but it didn't really make sense for them to be doing that.
So knowing about the research makes me more supportive of the MoD, because that is sooooo important. And this forum, with other online resources, help people who don't have access to MoD support at their hospitals. It doesn't seem to me that it's the MoD choosing whom to help and whom not to, rather which areas/hospitals provide them access.
