Just wanted to say, don't go crazy buying formula. Sign up for free samples with each company. Keep those on hand in case the baby does not do well with one until you have milk come in or need to supplement.
My neice adopted a beautiful baby girl, came home with formula from the hospital and ended up trying every one on the market before her mother and I convinced her to try to induce in order to breastfeed.
She didn't want to breastfeed, she thought formula would be easier and that other people would think ill of her to breastfeed an adopted baby. She is happily breastfeeding now, not that she didn't have problems with that. I wish she would get on this site for more support. If she is by any chance, I love you and am here for you any time, just call me.
Blessings to all!
