> I'd love to hear more about how a culture that doesn't name children under 5, do their child rearing and generally go about their life.

(Christian Orthodox, majority) Greeks don't name babies when born, only when baptized (usually during the first year, but could be later). Until then, they appear on formal documents as either "male"/"female" or as "AKO" ("no first name"). In practice, people either call a baby "the baby" or may sometimes use the (future) name informally.

The Catholic Church here in the US (at least, in San Antonio) will give you a second middle name at the time of your Confirmation. At least they did, back in the 60s.

My wife has a second middle name that you don’t usually see, not even on most official documents. But it is a part of her full legal name.
