Date nights are fun, but they require so much planning (the babysitter, the restaurant, the movies, etc.), that they take some of the spontaneity out of a relationship. If both parents work, get up and call in sick. While the sitter or day care watch the kids, make it a daylong date. Visit a museum, plan a midweek picnic in the park, or simply check in to a local hotel for an afternoon of bliss!
