There is alternative perspective of "Young Carers" or "きょうだい児" in Japanese.

I don't think it was a easy choice then, or easy choice now.

Here we have an interesting pattern where the childhood is actually a brittle thing:

If you have a good childhood you grow up into an well integrated adult with no issues. However, if you are having a bad childhood, not only you have the process disrupted for you but it also cascades into your family, in this case siblings. That's because the childhood is so social, and it is often the bad kind.

Many of non-neurotypical (or even physically disabled) children could grow up into integrated adults, it would just take somewhat more time. However, they often don't have access to that time as they are isolated and sidelined by the social structure.

Adult don't care about each other or meddle in each other's affairs, but children would. That's often deleterious.
