“…However, the NICHD study found that, while child care instability during the first two years of life was related to greater mother-reported behavior problems, this effect was no longer statistically significant by 3 years of age so the effects may be short-lived (NICHD Early Child Care Research Network, 1998). Furthermore, in order to better understand the effects of child care instability, it would appear important to consider a number of additional child-and family-related variables that have been found to be associated with children's behavioral outcomes, including the timing, intensity, and continuity of maternal employment during the preschool years (Baydar & Brooks-Gunn, 1991), the child's temperament (Stoneman, Brody, Churchill, & Winn, 1999), and reasons for changes in care such as marital dissolution, changes in patterns of employment, and residential moves (Ackerman, Kogos, Youngstrom, Schoff, & Izard, 1999;Hoglund & Leadbeater, 2004).…”
