We share with our 3 yo and we will have a baby in a few weeks. 3 yo is in our bed, but she won't be sleeping by Baby (only I will). Before about two weeks ago, our older boys (6 and 9) were sleeping on another bed in our room, as well. They have some health issues, which are now resolved, so they are (happily for all) in their room together. It was never a problem for us, and DH and I felt safer having the boys close to tend to their needs.
