critically discuss how family and peer relationships can impact cognitive and social-emotional development across the lifespan.

I was thinking for an essay in order to capture lifespan to first talk about household dynamics and its effect on later life in regards to cognition and social emotional development.

then speak about friends throughout school years and how those relations influence child's development outside of the home, positively and negatively.

then talk about romantic relations and so on.

If there's a better way of tackling the essay please advise me
