"Baby Bunching™ is two years of pregnancy and back-to-back infants and toddlers with nary a break for you. Baby Bunching means chaos for you, and your little twiblings. No worries, they become good friends as a result of your bunching strategy. You will become strong, creative, organized, calm and at peace with your new lifestyle without even realizing it."
