Level 3 - Intimate mutual sharing (8 - 15 years)Young children begin to demonstrate some acts of kindness, helping each other problem solve.
There are high levels of trust and loyalty but betrayal is considered if an individual has more than one friendship.
For some children, this is also the “Joined at the Hip” stage.
Level 4 - Mature friendship (autonomous interdependence) - 12+ years
At this stage, children place a high value on emotional closeness with friends. They can accept and even appreciate differences between themselves and their friends.
Young people who develop mature friendships are not as possessive as they might once have been, so they’re less likely to feel threatened if their friends have other relationships.
