Quite by accident, I attended a baby naming ceremony at a vihara which serves the Sri Lankan community in my home town. I had asked the resident monk if I could call by with some requisites.
When I arrived, a couple with their new baby were about to have the monks perform the ceremony. No one else was in attendance. I was delighted to be invited to sit in with them. The "service" included a reading, some chanting (I recognised the Metta Sutta) and the joining of all participants (including the baby), with thread.
It was quite brief and there was much smiling and a relaxed communal vibe.
I don't know if this helps Mawk, but I'm not big on rites and rituals. It was a very pleasant occasion.
