Congrats to you and your sister too! Her emotions sound much like mine when I found out, also after many years of trying and treatments. I also wondered if I could possibly breastfeed and stay home and so on and so forth.
There are some great books out there and I'll mention a few that I love:
1. Mothering Multiples by Karen Kerkhoff Gromada. This is an LLL book and it saved my sanity and preserved my breastfeeding experience (17 months and still going strong in spite of many many difficulties early on!). Also check out her website at www.karengromada.com
. She answers some of the basic questions twin moms to be have on the site, and the book has lots and lots of detail. Great stuff!
2. Having Twins by Elisabeth Noble is a classic in the field. My doctor, also a mom of twins, gave me her old dog-eared copy as soon as we found out I was carrying twins. It was a great read and hugely encouraging. The book is recently out in a new edition and though I haven't seen that it comes highly recommended by those who loved the old edition too.
Another book and website that will help her navigate her pregnancy is When You're Expecting Twins, Triplets or Quads by Dr. Barbara Luke and Tamara Eberlein. This is primarily about multiple pregnancy and is not as heavily promoting of breastfeeding as some of us might like. But her nutritional information is cutting-edge research-based and she's a gem. She also runs a nutritional service at her website, www.drbarbaraluke.com
. I signed up for this and got weekly nutritional counseling, lots of phone support during my many complications, and I just can't say enough about Dr. Luke and what she's doing for twin pregnancy. A word of warning though - no information on working with a midwife in this book, if that's the way your sister is going I think the Elisabeth Noble book is more directed that way. But Dr. Luke's book is a must-read for info on what to do in the case of problems and how to manage your nutritional needs so that your babies can be born healthy and as close to due date as possible.
I'm sure others will chime in with their reviews of these books and recommendations for others. Good luck and congrats and to your sister - welcome to the wild ride that is twin pregnancy!
