Family is the most important thing. If you get along, then what is the question? Kids will benefit from being with their grandparents. You do have to prepare yourself mentally. It’s not going to be your house and maybe other siblings and their mishpacha will be there. So: be flexible, smile, offer to help, smile,
watch your children and pick up after them, smile. Clear the table, smile. It is not a vacation. It is a Yom tov. Everyone should have a laid back attitude. Enjoy the family. This is what it’s all about.
