Wishing Box or a Signature Book
It can happend when each guest arrives at the naming ceremony or at some time during the proceedings of the day. Each guest and family member writes a note. The note is to the child and places it into a special wishing box. This note contains messages. Messages such as special wishes, hopes and desires for the child or even a personal message.
As the child grows, on their 18th or 21st birthday they can open the box. The Message Box is then available to the child. The child then can read those special wishes and messages written down and placed in the box at their naming ceremony. The most popular time in life to present the box to the child seems to be a twenty-first birthday.
It is also lovely for the parents to go through the notes on those quiet nights together as their child is growing up.
