“…Our data for this case study are the original four empirical studies of overnights that included children four years and younger (McIntosh, Smyth, & Kelaher, ; McIntosh, Smyth, & Kelaher, ; Pruett et al, ; Solomon & George, , ; Tornello et al, ), along with 26 papers published within the past five years that included 12 reviews Cashmore & Parkinson, 2014; Kline Pruett, McIntosh, & Kelly, ; Lamb, ; McIntosh, ; McIntosh, ; McIntosh, Kline, Pruett, & Kelly, ; McIntosh & Smyth, ; Neilsen, , ; Smith, Caffino, Van Horn, & Lieberman, ; Solomon, ; Warshak, ), 9 critiques or commentaries (Garber, ; Hynan, ; Lamb, , ; Ludolph & Dale, ; Ludolph, ; Millar & Kruk, ; Smyth, McIntosh, & Kelaher, ), and 5 replies to critiques (Tornello et al, 2013; McIntosh, ; McIntosh, ; McIntosh, Smyth, & Kelaher, ; Parkinson & Cashmore, ) on these studies and on the subject more broadly. Each of the four single studies tested specific hypotheses about the association between overnight stays and indicators of young children's security of attachment, proxies for emotional regulation and/or emotional‐behavioral functioning.…”
