Bed-sharing is pretty prevalent in most parts of the world, but tends to be quite controversial in the United States. While more than a few parents assume it's dangerous I, personally, think it's the best damn thing ever. Still and even in spite of all the pros that made bed-sharing the right sleep situation for my kids and my family, there were things I wasn't ready for after I started bed-sharing, too. Little surprises, if you will. In the end (as with everything else associated with parenting) the baby books can only prepare you for so much.
When I first started bed-sharing, I was doing so thanks to an overwhelming amount of sheer desperation. My baby hated sleep and loved nursing and I was losing it. I was exhausted and stressed and about to snap. One night, I'd had enough and gently put him next to me in bed. It was bliss. I slept better than I had since before I got pregnant, in fact. Since that night, there has been at least one kid (and sometimes two kids) in bed with me and my partner, and I've taken to using the term "family bed" pretty frequently as a result. Bed-sharing is our norm. We follow the rules for doing it safely, and it has been a huge boon.
Even though I loved bed-sharing from the minute we started, there were a few surprises along the way, and more than a few things I wasn't exactly prepared to experience. I guess I can just chalk the entire "surprise factor" of bed-sharing to the undeniable fact that no matter what, motherhood is going to throw you more than a few curve balls. Yay.
