[Grammar] so do their children.

[yi-ing]

Is this sentence correct? If so, what kind of grammar rule is bold part? I am going to google and get deep understanding it.
I appreciate it if you give me a source for studying.

Parents spend less time with their children, and so do their children.


Thanks.

Is this sentence correct? <snip>
Parents spend less time with their children, and so do their children.

It's grammatically correct but logically impossible. How can the parents' children spend less time with themselves?

Opps!!!I am really sorry for making such mistake.
I meant:
"Parents spend less time with their children, and so do children."
I want to say, children spend less time with their parents as well.

It still doesn't work. And so does/do tells the reader to repeat the previous clause with a different subject, so this version means Parents spend less time with their children, and children spend less time with their children.

You can express these complementary ideas as Parents and children spend less time together than they used to.

If that is the case then I would write the sentence this way:

Parents and their children spend less time with each other.

 

[tedmc]

Parents spend less time with their children and vice versa (meaning the reverse is also true).

Parents do not make time for their children and vice versa.

 

[yi-ing]

Parents spend less time with their children and vice versa (meaning the reverse is also true).

Can we use "vice versa" in an academic essay?

Yes. It's formal English.
