From 2 to 5 in 4.5 years

Four-and-a-half years ago my wife and I left the South Bay and moved into our small two-bedroom Peninsula condo, a family of two. Tomorrow we move out and move back to the South Bay, a family of five. We never expected our family to grow so fast.Our family more than doubled in four-and-a-half years. We went from one man and one woman, to four men and one woman.We went from 2 to 5 in 4.5 years.
