I have a permanent reminder of my son every time I look down. On my sternum (chest) I have a huge memorial tattoo for him. It hurt like hell but not nearly as bad as the loss of him.....
Also, DH bought me a nice Celtic locket with double sides, I have a picture of Roman on one side and a pic of Brad (my DH) on the other
EDT: Cubitus, Mei Filius is Latin for Rest, My Son......I chose latin since I have a memorial tattoo for my brother who committed suicide. It says Sacrificium, which is Latin for Sacrifice...(this one is on my shoulder blade, left side)
