My family did this for years. We didn’t have the resources to take on a full child, so we had teens spend the weekend with us. They slept on the couch, but got the chance to have a fun weekend, full home cooked meals, and someone to support them. The last child we fostered from 15-18, helped him getting into college, my dad gave him his old car. He’s now 35, married and rather successful. Any help is some help
