Summary Yes, you are seeing double, triple and quadruple. Over the past decade, the incidence of multiple births has increased tremendously, thanks to the success of modern reproductive technology. In this feature report, we meet the Harrisons, parents of quads and the Scotts, who have triplets and, Dr. Johnathon Barrett, an OBGYN at Women's College Hospital for a look at the medical, lifestyle and financial realities of having multiples. Parental softie Alex Sopinka resolves to stop being a "yes Daddy" to his irresistible, and wiley, daughter Zoe in this Reality Check. We all struggle to learn how to manage and save money, but in this "How To", financial writer and parent Gail Vas-Oxlade tells us how to start early with our own kids, with some sound advice on teaching our children the value of money. Tara and Bill Mummery resolve to get their two young sons' TV viewing habits under control. So, they declare a TV-free week and document the process for this Video Diary.
