For children who have not yet found that special friend, there are still plenty of opportunities ahead. Friendships change all the time throughout childhood, says Graber. When best friends drift apart or move away it can be difficult for young children, who aren"t used to relationships ending. "There isn"t a ritual for children to grieve the loss of that relationship," she says, adding that it is important that parents discuss this with their children and support them through the process.
