The Baby Borrowers premiered on NBC on June 25, 2008. Baby Borrowers is a unique social experiment that takes five teenage couples on a rollercoaster ride of adult responsibility, allowing them to experience parenting firsthand. Desperate to have their own life and family, our lovebirds are thrown in at the deep end. They're given real houses and real responsibilities - the most important of which is to look after children from a range of age groups. They'll begin with an infant, followed by a toddler, pre-teen, young teenager, and lastly a senior citizen. In the end, will these couples be able to cope with the pressure of parenthood or will they break?
