Thank you jakesgal88. I already have the babies and the first book will be a great source.
A couple good books i've found are "Mothering Twins" and "What to Expect When Expecting Twins, Triplets, Quadruplets" The first one has more on after the babies, but a little bit about the pregnancy. The second is loaded with all kinds of good info on the pregnancy and focuses mostly on that, but then has a bit about after the babies come. Hope you find these helpful.
