I was raised like this (of Russian background) but I will not have the same benefit, there is no extended family from either side anywhere near me or my partner. And this applies to most of my social circle, all of whom have moved around for career and/or restlessness.

It's nice to finally understand that yes, for a couple (especially where both have careers), raising a child is harder than it should be and harder than it used to be, because of this lack of tribe, and no we are not just self-pitying moaners. I don't think this trend is going to reverse itself, which makes me hope in some vague way that some sort of communal tradition emerges, where the tribe is formed by some social grouping (close friends) other than the extended family.
