There's a rule:
The 'to' is optional in several similar constructions:
All I want to do is (to) turn it . . .
What I want to do is (to) turn it . . .
The best thing to do is (to) turn it . . . (easiest, first, next, etc.)
Doesn't the rule above apply here?
My main concern is to raise my children
My main concern is to raise my children No. That is a non-standard use of "concern"; concern implies apprehension. People do use it that way, but it bruises the grammar to the point where any further awkwardness is unimportant, and the full infinitive is just as clunky as the bare one.
