Answer:sibling rivalry
Explanation:
What is sibling rivalry?
This is an animosity and fighting between sibling that occurs due to the arrival or birth of a new child in a family .
The first child or older child may feel a bit of jelousy for this new born child and this start as soon as the child is born.
The older child may feel like their parents like this child more than they love him or her because of this they may act spiteful towards their sibling .
To them this may feel like the only way to take out these frustrations by being mean to their siblings.
