Hi and welcome! Two recommendations real quick:
1. Get Mothering Multiples by Karen Kerkhoff Gromada. Also check out her website at www.karengromada.com
. This book is a lifesaver and has lots of tips. The website has a photos section which is awesome and at least one of our moms from this forum is featured there. This is an LLL book so you know you can trust the content.
2. Pregnancy books worth getting: When You're Expecting Twins, Triplets or Quads by Dr. Barbara Luke and Tamara Eberlein (also Dr. Luke's website at www.drbarbaraluke.com)
. Make sure to get the current edition, which includes recipes. Many on this forum credit Dr. Luke's nutritional information with the success of our pregnancies. Also a classic, Elizabeth Noble's Having Twins, recently out in a new edition (but I read the one from 1984 and loved that one too).
Regarding gear, everyone has different solutions. We ended up using some gear and discarding some. In almost every case we had things donated to us by friends, so buying this stuff in advance is not worth it unless you know no one with children. :LOL Scan this forum for ideas on not just slinging twins but finding slings for twins (I don't have that sling so can't refer you directly but there are both links and photos here on this forum).
It's a bummer you got flamed elsewhere. Hang out here. You're going to do great. Twins respond very well to AP. They are people like everyone else, LOL.
Welcome! Eat and rest, eat and rest, eat and rest! Congrats on your pregnancy!
