原文：
Psychiatrists (精神病专家) who work with older parents say that maturity can be an asset in child rearing-older parents are more thoughtful,use less physical discipline and spend more time with their children.But raising kids takes money and energy.Many older parents find themselves balancing their limited financial resources,declining energy and failing health against the growing demands of an active child.Dying and leaving young children is probably the older parents’ biggest,and often unspoken,fear.Having late-life children,says an economics professor,often means parents,particularly fathers,“end up retiring much later.” For many,retirement becomes an unobtainable dream.
