How much time away from your LOs do you get? Not including work/school and commute.

Dh & I have only been away from the kids once for a family thing and once for breakfast when running an errand in the past four months since having our second. I know we need more us time but cold/flu season and having two (so not wanting to let MIL watch both at the same time) are preventing us from getting out. Wondering what a realistic goal might look like. With one we got out almost every month.
