These are special times in the childs life and for the families involved. 
I have made Christening presents for the child, and for the godparents. These have had the date and the childs name on them.

The Bar Mitzvah presents have been very special for the 13th Birthday of the boy , who then assumes full religious obligations. I have made the young man dog tags with their birth date on and the parents and grandparents have had keyrings or charms made with the young mans date of birth on.

Wedding Anniversary pendants and Keyrings are popular especially for the 5th Wedding Anniversary which is Silverware. So wear Silver!
