When You’re Expecting Twins, Triplets, or Quads by Dr. Barbara Luke, Tamara Eberlein, and Dr. Roger Newman, Fourth Edition. This book was my Bible during my twin pregnancy - I read it cover to cover and referred to it often. So much information and guidance. Looking forward to passing it on to a future mom of multiples! Good used condition but there are some marks on front and back cover and a few earmarks on pages - because, like I said - so much good information! Bundle to save!
