One interesting thing is if only one parent speaks the second language then kids will tend to only (obviously) pick up the tendencies of that speaker.

So if a dad then the kid, irrespective of their gender, will pick up dad’s masculine tendencies or if mom her feminine tendencies. (dad may say the equiv of "dude" and mom may say the equiv of "guys", those sorts of things.)

It’s not good or bad. It just is.

Yeah, it's very context sensitive. My father in law learned Hungarian as his first language in a Hungarian neighborhood in Cleveland. When he went to Hungary decades later they told him he spoke like their great grandparents.
