Updated in 2020. With almost two times as many sets of twins today as there were forty years ago, What to Do When You're Having Two has quickly become the definitive resource for expectant and new parents of multiples. A mom of fraternal twins and a world-renowned expert on parenting multiples, author Natalie Diaz launched Twiniversity, the world's leading global resource for twin parenting information and support online. Now, with her expanded edition of What to Do, she includes new information on breastfeeding, gear, sleep, and having two when you already have one, as well as: creating your twin birth plan; maintaining a realistic sleep schedule; managing tandem breastfeeding; stocking up on what you'll need (and knowing what high-tech products are now available and what's a waste of money), and building a special bond with each of your twins. Accessible, informative, and humorous, What to Do When You're Having Two is the must-have manual for every parent of twins.
