My impression from bein in east Asia is that a child is considered really a person until it is a year old and really young children (toddlers) were not considered much of a person. After child got to be about 5/6 the family really doted on them in a way most Americans would think a bit much. But then little east Asian kids are often just absolutely delightful.
Whether a child is delightful, or a monster depends on how it is socialized.
My mother, born in 1917 told me that although children may have been named at birth, they often were not called by a name until it was clear they were going to survive childhood. She and everyone she knew had experienced childhood deaths among neighbors, family and friends. It wasn’t unusual that of four or five children one or more died early. So, not considering a child a person, even though it was now likely they’d survive childhood may be something engrained in the culture.
My mother said that her father, born in the previous century, told her that in his childhood many children were not named until they were almost adults and then, they often chose their own names. His family was German, so I don’t know if that datapoint is from Germany or Ohio.
For some context, during the moon landing in 1969 I yelled from the living room to the kitchen where my mom was working, “Mom! They’re about to step out on the moon!” She yelled back, “I saw Orville and Wilbur Wright perform at the Ohio State Fair.” From her context, when the whole town would run outside to wave and yell at a passing plane it was equivalent to the moon landing.
