Social-emotional development includes the child's experience, expression, and management of emotions and the ability to establish positive and rewarding relationships with others (Cohen and others 2005).

It is the development of being able to: Form and sustain positive relationships. Experience, manage and express emotions. Explore and engage with the environment. credits: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=11&cad=rja&uact=8&ved=2ahUKEwjflcDVpvjoAhXMFIgKHSWJCKgQFjAKegQIARAB&url=http%3A%2F%2Fhelpmegrowmn.org%2FHMG%2FHelpfulRes%2FArticles%2FWhatSocialDev%2Findex.html&usg=AOvVaw3Yq38uxXXOme7edGb7VCya
