A family get together can be made even without going out of the house. The usual weekend getaways can sometimes be out of the budget. A simple lunch or a picnic in your own lawn can be done. Household chores can also be utilized as a family bonding activity.
Painting the house is one example. Instead of hiring painters, why not let the big kids do it with the guidance of their father. Mother and the girls can prepare the snacks. Another one would be teaching your children how to operate the push lawn mowers and then afterwards picnic can be done. Simple yet productive activities that are at the same time cost efficient.
