According to Patricia Estess, the first landmine is relying too heavily on a former spouse for child support. Being dependent makes you vulnerable. The second is skimping on the new family and spending on the old. Throwing money at your kids won’t erase guilt or make up for lost time. Honor all your commitments equally. And third, don’t have two different financial standards. Share your resources and treat everyone the same. When it comes to monetary landmines in stepfamilies, step around them.
