This may take the form of eagerness for reunion or a dread of a return to a problematic situation or a mixture of both. Few get much sleep the night before homecoming. Children in the home may act out more than usual. These feelings may result in you and your family members being key-up and exhausted when the family is finally reunited. It may take a while for the military member to get adjusted to the local time zone, home cooking, lack of continual aircraft noise, etc.
Some initial difficulty sleeping through the night is typical.
Reality is seldom equal to how we have fantasized life after reunion would be. It makes sense to keep expectations reasonable and to be flexible. Skillful compromise and reasonable give and take will be needed if arguments and hurt feelings are to be avoided. It is wise for the military member to express appreciation for the spouse's efforts in running the household single-handedly. It is unwise to criticize the spouse's efforts or the decisions they had to make own their own during the deployment.
