The costs of providing clothing for a family of children who are constantly growing can rack up. Every new season will require a new wardrobe. Big families are used to the age-old cost-saving rituals of hand-me-downs, which is passing clothes down from one child to the next as they grow. It's nothing to be ashamed of and a great way to encourage family unity and cooperation. Also, consider sharing clothes with neighbors and friends.
Along the same lines, it's a good idea to consider buying used items. Thrift stores and consignment shops are great places for bargains if you have the time and patience to search them. And this goes beyond clothes. For every big purchase, think about whether buying used is feasible.
