For babies from several-month old to 4-year old, most of them get their parents frustrated(e.g. most babies often cry). But I heard of true stories of several babies. These true stories have the following common or similar parts about such babies:
After being left alone, such babies usually don't cry. He/She can play with himself/herself quietly for several hours.
When introduced by parents to a stranger, most babies are shy and even cry if they are taken in the stranger's arms. But, unlike most babies, such babies usually don't shy, and don't cry in the stranger's arms. Such babies do what parents tell them to do (e.g. say hello or wave hands to the stranger), and even smile to the stranger.
Such babies usually do what parents tell them to do. For example, most babies cry when they are given an injection by a doctor. But, unlike most babies, such babies usually stop crying after parents just coax them with only a few words.
Honestly, I'm not sure about the following things:
- I'm not sure whether such babies have more common/similar stories.
- I'm not sure whether these stories or similar stories are sufficiently common. (I'm trying to collect more true stories or similar stories, if any, and post them here later).
I'm interested in the following topics:
- Do such babies have any common/similar stories when they reach adolescence (or adulthood)?
- If above stories are sufficiently common, then what are the factors behind these stories?
- If above stories are sufficiently common, are there any special terms or phrases for describing such babies?
My question is: Is there any study in the science (e.g. Psychology, Pediatrics, Medicine, and etc) about above true stories of such babies?
It would be better, if there is any study on my interested topics mentioned above.
