It's difficult!
We have close relatives in France and Japan. Previously, we were able to visit our relatives once a year in Paris and once every 2-3 years in Tokyo. My parents flew to visit us once a year. Visits are 10 to 15 days, as they are the maximum DH can take off and the maximum I can stand my own beloved but crazy mother
However now with 2 children and reduced means, we cannot visit as frequently, which pains me because I do so want my youngest to meet her great-grandmother before she passes away. We are saving money aggressively towards that particular visit, but it may still not happen in time.
Do your best, OP. With scattered international families, sacrifices have to be made.
