Ways to honor the loss from miscarriage/still birth

Back in 2007, I ended up having two miscarriages. Both times I didn't know I was pregnant. A month after the second one, I was seeing my GYN for the first time because of debilitating cramps. I also ended up talking to her about what I believed were 2 miscarriages and went into full detail about the events. She informed me that a pregnancy test would still reveal if I had been pregnant or not because my hormone levels would still be changed from pregnancy. Sure enough, I had been pregnant.

I didn't acknowledge the losses until 4yrs ago. I heard about how giving a name to the lost life helped someone grieve and heal. I looked into it more and read up on naming ceremonies. (I wrote about that here https://endometriosis.net/stories/naming-ceremony-for-miscarriages )

I came across a list of other things to do to help with grieving and healing. This can also be done for still births too. They are in no particular order:

1) Naming ceremony
2) Make or wear memorial jewelry (I'm currently having a special ring made in honor of my two miscarriages)
3) Write about your baby
4) Plant a tree or memorial garden
5) Get a special teddy bear or other stuffed animal
6) Donate to a charity in their honor

Have you done any of these or other things?
