It looks like the Sleep Wars have begun. Several weeks ago, in a column on attachment parenting, I wrote “James J. McKenna, director of the Mother-Baby Sleep Laboratory at the University of Notre Dame, says that he has yet to find any benefit to parents and children sleeping together.” I arrived at that conclusion after reading an online Q/A in which he wrote “The truth is that there is no one outcome (good or bad) that can be associated with co-sleeping in the form of bed-sharing, but rather a range of outcomes (from potentially beneficial to dangerous and risky) depending on the overall circumstances within which the co-sleeping takes place.”
