“…In interacting with each other, siblings can reinforce or discourage learned behaviours and skills, with both positive and negative implications (Kramer, 2010;Parke & Buriel, 2006). Sibling interactions can promote prosocial behaviours such as helping each other learn how to share and take-turns (White, Ensor, Marks, Jacobs, & Hughes, 2014), to develop social reasoning (Dunn, 2002), to enhance emotional and cognitive development (Campione-Barr, Greer, & Kruse, 2013;Prime, Pauker, Plamondon, Perlman, & Jenkins, 2014), to safeguard against internalising problems, and to increase levels of self-regulation in adolescence (Padilla-Walker, Harper, & Jensen, 2010). In this way, siblings are developmentally advantageous and provide an important interactional context to helping individuals acquire crucial life skills.…”
