For sleeping patterns, many parents wonder if they should start out with their twins sleeping together in the same room, in the same crib, or if they should sleep in different places. My experience in working with many sets of twins is that one twin waking and crying, even for an extended period of time, doesn’t usually awaken the other twin. They are used to one another’s noises and don’t easily awaken each other.
Even when they sleep in the same crib, their noises and movements don’t usually awaken each other if they have been in the same crib together most of the time. I have seen newborn twins turn their heads toward each other in the crib, and be soothed by their closeness. I think having them sleep together can help them learn to be more flexible and not wake up at the slightest noise.
