Being a parent, I know how important it is to get alone time after the kids are in bed. It's really what keeps me sane throughout the day, knowing once I get my girls down I can spend at least an hour doing what I want to do. Reading, coloring or watching a show. Of course DH and I hang out sometimes too, but if he's busy with work it's nice to just enjoy the time alone. So I aim for at least an hour, but usually get 2 or so hours every evening.
