Kristy,
Again I am so sorry for your loss.
My SIL lost two late term babies - one at 24w and one at 27w because of an incompetant cervix.
Sometimes I am amazed at her strength to get through it all, but her babies are still a very big part of her life.
The grave at the cemetary is covered with toys, andthese are changed with the seasons. Its very much a rememberence spot for her. Whenever we go to the cemetary, we always sneak a little chocoloate for the girls, and everyone on both sides of the family acknowledges the loss.
In addition, my SIL has photos of the babies on the walls of her house. While it makes me feel a little uncomfy, I understand that she needs to do this for her heart, so we just go with it. All presents and cards etc are always signed from the babies, as well as her living 3yo, and we just accept it.

I guess what I am saying is that some people choose to live with constant reminders of their angel babies, and some chose to hide it away. You need to do what is right for you and your DH in order to remember Harrison. And if that seems to be against the grain of what normal society expects, who cares. Its your loss, and you have the right to mourn as long and in whatever way you choose.

I'm thinking of you, and wishing you strength at this tough time.
