Hi, this is asking you to take a look at the theorist John Bowlby. Search online and on the forums here -
search page to find other posts made regarding attachment theory. Gradually you'll see how his work links in with some thinking on practice that, for an example helps children's transition from home to setting - leaving mum or dad, taking comfort from familiar objects/soothers, teddy, blanket. How the reassurance of having familiar or significant people/person around can give confidence to children and support their developing independant participation.
