I think Chinese and Korean culture share this concept, and I wouldn't be surprised if there were more Asian languages who did. Since a daughter joins her husband's family upon marriage, their children are considered belonging to the other family. I recently learner that apparently there's a saying in Korean that daughters always leave things at their mother's house when they get married so they have a reason to come back despite having left the family.
