How much of parenting is about individual effort and achievement? One writer explores this theme in the context of feeding an infant:

Some of these comments excessively attributed a positive outcome to personal influence and merit. Others obscured good fortune while elevating narratives of bold triumph over one’s circumstances (even though the former was a prerequisite for the latter). What they shared, though, was a focus on individual agency and control that seemed rather incongruous with the reality of becoming a parent.
For most people, becoming a parent (or merely trying to become one) represents a headlong leap into an existence of radically diminished control over high-stakes outcomes. To successfully welcome a child into a family, whether by adoption, surrogacy, IVF, or paleo-style conception, relies on the cooperation of many factors that lie beyond our control. Getting pregnant is not as easy as pulling an all-nighter to finish a presentation, carrying a healthy pregnancy to term is not like training for a half-marathon, and having a healthy newborn is not like acing an exam, although our expectations of agency may be anchored to such prior experiences with goal achievement.
What accounts, then, for these tendencies to assume personal agency and overlook external factors, especially in life chapters when so much is out of our hands? I nominate Western individualism, the myth of the American dream, the platitudes of self-help and positive thinking, and the justifications of meritocracy…
One of the great puzzles of parenthood, and life in general, is learning to accurately draw the boundaries of our control and act accordingly. Within those boundaries, plenty of opportunity remains to exercise judicious self-efficacy and responsibility for our actions. But so many crucial outcomes rest at least partially on factors beyond our bubble of agency. And when their influence is in our favor, the soundest response is not meritorious pride but humble gratitude.
Sociologists describe the two sides described above as agency and structure. Individuals have choices they can and do make. Structures – institutions, systems, groups and networks, etc. – organize the world and constrain or empower actors. Compared to the American perspective described above that tends to emphasize individualism and outcomes based on one’s own efforts, sociologists tend to emphasize structures and the ways individuals and actors are situated within them.
Parenting provides an interesting context in which to consider this: babies are dependent on adults, but how much influence do parents have in the long run? Some but not total. And parents are influenced by particular contexts and their own settings. Yet, it would likely take a long time for American parents to move to a perspective emphasizing structures in raising kids.
