David Bain goes through 10 gallons of milk and 40 loads of laundry every week. That's because he and his wife have 13 kids. They're foster parents - taking in kids who have suffered from neglect and other abuses. So besides a big fridge, what does it take to raise a foster family? How do you navigate carpooling and taking your kid to family court? How do you deal with biological parents with drug addictions, and how do you hand a child back to her family after she has lived with you for years? We talk to David Bain and other foster parents about what it takes to make a family.
