If you have just found out your child is bullying other children your first reaction might be disbelief or anger. But there are calmer and more effective ways to stop your child bullying.
Reasons for bullying:
If your child is bullying, they could be copying the behaviour of other people in the family; or perhaps they haven't learned better ways of mixing with their friends. Friends may be encouraging bullying, or your child may be going through a difficult time and acting out aggressive feelings.
To stop your child bullying:
Explain to your child that what they are doing is unacceptable and making other children unhappy
Discourage other members of your family from using aggression or force to get what they want
Show your child how they can join in without bullying
See your child's teacher to talk about how you can work together to stop your child bullying
Check regularly with your child about how things are going at school
Give your child lots of praise when they are co-operative and kind to other people
