We are new to the area, our nearest family is an hour away (and stresses is out) and will have a newborn in January. We won't actually be leaving him alone by February, but once we do, we'll want to know who to call. And it's possible we may want to enlist some help with chores before then, or just someone to come over and let Mom get some nap time after I have to go back to work.
Once we're comfortable leaving him alone we just want to be able to go out for dinner occasionally. Our needs will get a bit more ambitious as he gets older, and once the two special needs 5 year old twins join us after the end of the school year.
