We did not co-sleep. Our oldest was adopted from China, and many times the children in foster care do co-sleep with their foster families. Our daughter was actually sleeping in a crib in her foster home, and that is what we continued when she came home with us. Our youngest slept in a bassinet in our room for the first few months and did occasionally end up in the bed with us part of the night when I was nursing (or later if she was having trouble sleeping). Now that she is bigger and moves around a lot in her sleep, she doesn't end up in our bed nearly as often. After the bassinet, she moved into her own crib in her room.
