I second the boba, I love mine, and if I am crazy enough my 4 yo still fits well in it. So you'll get your $ worth. If you are afraid of putting her on your back I think the beco butterfly has an internal harness or something to make it easier. With my boba though I just put one strap on, slide my dd around and pull her leg through leaning over, and pull the other strap up. Just keep practicing, it gets easier.
