Talk openly about how your family earns and spends money (i.e. "Mommy has to work to make money for our family" or "we're not going out to dinner this month because we're saving money for our trip next month"). Be sure to present a united front with your coparent and keep money disagreements behind closed doors. Also, avoid expressing major stress or fears about money. Your children are likely to internalize that anxiety and misunderstand what part they play in it.
