Away We Go (2009) on Netflix

Mid-thirtysomethings Burt Farlander and Verona De Tessant are a loving couple. Burt has always wanted to marry Verona, but Verona resists, not seeing the point of the institution. Regardless, they are having a baby together, despite questioning their potential parenting abilities. They are happy that they made the decision to move close to Burt's parents, Jerry and Gloria Farlander, as they want to share the experience with the baby's grandparents. Verona's own parents died over ten years earlier, a situation about which she doesn't like to discuss. In Verona's sixth month, she and Burt learn that Jerry and Gloria are moving to Antwerpen, Belgium the month before the baby is due, just because it's something they've always wanted to do. Burt and Verona don't understand what they see as Jerry and Gloria's selfishness in putting this move above spending time with their impending granddaughter. Being mobile people, Burt and Verona decide to move. As they want to share their new family experience with people that they love, they decide to take a trans-continental trip to meet with old friends and relatives. Most of them are married with children of their own, and Burt and Verona want to see where they would like to live and with whom they want to share the experience.
