But there were times I'd be home alone with a baby 8 hours many days each week.
Now it's just me and the younger one sometimes, when she isn't in preschool. Maybe 6 hours two or three times a week. No, even then we spend a good part of our time at the park/library/museum/etc. I guess not much anymore.
So in addition to saying how much you're home alone with your kids, maybe say how old they are, and whether they go to school or you homeschool.
