“…The adopted conceptualizations insofar, viewed cosleeping as a sleeping arrangement where the child slept either with both parents or with the mother (e.g., Kaymaz et al, 2014;Keller & Goldberg, 2004;Santos et al, 2017;Teti & Crosby, 2012), apparently adhering to the attachment tradition (Ainsworth, Blehar, Waters, & Wall, 1978;Bowlby, 1982;Cassidy & Shaver, 2010). However, as Ross, Hinshaw, and Murdock (2016) pointed out, attachment theory "may be overlooking the role of a second parent in psychological well-being" (p. 400), thereby a co-sleeping conceptualization from an attachment standpoint is limited in its dyadic focus and neglectful of triadic-level interrelationships.…”
