Different ages

Older children tend to be less jealous than their younger sibling. This is due to their ability to mentally process the social situation in a way that gives them more positive, empathetic feelings toward their younger sibling. Older children are better able to cope with their jealous feelings toward their younger sibling due to their understanding of the necessary relationship between the parent and younger sibling. Older children are also better at self-regulating their emotions and are less dependent on their caregivers for external regulation as opposed to their younger siblings. Younger siblings' feelings of jealousy are overpowered by feelings of anger. The quality of the relationship between the younger child and the older child is also a factor in jealousy, as the better the relationship the less jealous feelings occurred and vice versa.
