However, over time, scholars expanded their definitions to include single parents in multigenerational homes (Deleire & Kalil, 2002; Oberlander et al., 2007), custodial and non‐custodial single fathers (Alemu, 2019; Black & Keyes, 2020; Bronte‐Tinkew, et al., 2010; Coles, 2002, 2009; Edin & Nelson, 2013; Roy, 2006), and single mothers “by choice” (Bock, 2000; Carone et al., 2017; Golombok et al., 2016; Hertz, 2006, 2011; Jadva et al., 2009).…”
