You might also think about setting up a "co-op" with somebody where you take turns watching each other's kids (that is...if you meet another couple that has a similar situation that is interested in date nights). We have been switching off with some friends that have 3 kids, and we have 2 kids. The kids love it because they all get to play together and every other week (or so) we get a date. Just a thought...
