Let's read a book, it will calm you down," "Go, play on the trampoline, it will help you feel better," "Come cuddle, it will soothe you." Parents use directives like these every day, to teach their children various strategies for regulating their emotions. In selecting and using strategies for emotion regulation (ER), there is no onesize-fits-all solution, as children might react differently to strategies proposed by parents or teachers, depending on their age, temperament, the adult's or their own current mood state, and probably other factors. Research is scarce on identifying specific components. The present study, therefore, investigates relations between toddlers' temperament, their ER strategy distraction and possible learning mechanisms through observational learning.Emotion regulation is fundamental in mastering every-day challenges and life in its entirety, including physical and mental health, personality, and relationships (Gross, 2007;Koole, 2009). ER can be defined as "the process of modulating the occurrence, duration, and intensity of internal states of feeling (both positive and negative) and emotion-related physiological processes" (Morris et al., 2017, p. 1). Put simply, ER is one's ability to regulate one's feelings. It is assumed to play a key role in the development and maintenance of mental well-being and mental disorders (e.g., Feng et al., 2009;Hannesdottir & Ollendick, 2007;Suveg & Zeman, 2004). There is empirical support for this assumption. For example, in prospective studies with children, adolescents, and adults, maladaptive ER strategies predicted psychopathology (Abela et al., 2012;Aldao & Nolen-Hoeksema, 2012;McLaughlin et al., 2011). Not only has maladaptive ER been linked to unfavorable outcomes, but adaptive ER has also been related to favorable outcomes, such as social competences in young children (Blair et al., 2015;Denham et al., 2003;Spinrad et al., 2007). In sum, there is consistent evidence that ER plays an important role in children's emotional and social development and mental health (e.g., Aldao et al., 2016), but that ER strategies are wide-ranging and dependent on individual factors. Hence, understanding factors that shape early ER and
