I think the guilt becomes less and less over time as they get older. Trust me, when the girls were younger, they would scream and cling to me and beg and plead for me to stay. It absolutely broke my heart. But as it became more of a habit, they realized that mom always comes back. That guilt is still there when I go out on music nights, but after years of doing it, I know now that the benefits outweigh the guilt by far.
