Baxendale Walker provides tips for families to reduce expenses and manage their household budget during economic recessions. They recommend creating a monthly budget that tracks income and allocates funds across categories like food, housing, and entertainment. It is best to pay with cash instead of credit cards to better track spending. When considering purchases outside the budget, it is advised to wait 24 hours to avoid impulse buys. Additional tips include saving an emergency fund, paying down high-interest debt, lowering utility costs, saving on groceries through meal planning and gardening, and reducing entertainment costs by enjoying free library resources and staying in more. Making changes together can help families increase savings and limit wasteful spending during difficult financial times.
