Welcome Saddiejaney! Congratulations on your upcoming new little one! Sounds like things are pretty hectic over in your house! I hope that the 2nd tri comes along quickly and smoothly!
I wanted to let you know, there's a thread for non-bio moms who are inducing lactation found here: http://www.mothering.com/community/forum/thread/1224457/inducing-lactation
It doesn't come up all that often, but if you have questions or thoughts there are several mamas there who have induced. There also somewhere is a thread for all mamas who induce lactation, somewhere on the breastfeeding challenges forum, I think. There's some great info all around, so I hope you enjoy being more than a lurker on the boards! Welcome!
