Infant Rites of Passage
Having an 11-month-old of our own, Tatiana and I pick up lots of little pieces of information regarding 'exotic' traditions associated with newborns. There are several rites of passage that people commemorate for infants within the first year or so of their life. These typically include crawling, speaking, walking, and solid foods.
Cultures seems to celebrate (or ignore) such milestones in their own way.
Tatiana tells me of a tradition in India where the entire family takes hierarchical turns feeding an infant a small spoonful of food for baby's first meals of solids.
Here in Bulgaria, we've been told how when a baby beings to crawl a blanket with several objects is placed in front of the child, each with a specific symbolic meaning. The child then crawls over to the objects and chooses their supposed (professional) destiny in life. (Don't they do something like this for reincarnation-tests of the Dalai Lama?)
Georgi, our current host, tells us of a tradition involving a loaf of bread covered in honey that's rolled on the floor to celebrate a child's first steps. It's actually quite a large event, bringing together an entire extended family as part of the festivities.
I'm still searching for a comprehensive resource that might've cataloged such things across a variety of country or ethnic groups. If you know of one, please reference it in the comments.
