We had some good friends visit Savannah recently. When Anand's first son was born we made him a silver guitar pick necklace with his son's initials and birth date.
As "H", as he's called, got bigger he noticed and grew fond of daddy's necklace, especially because he knew it was his initials. Dad made arrangements for us to surprise him with a mini version of his necklace. Based on H's smile I think he was pretty happy with the result. Here are some links to the items they had us make for them:
