Please outline what is going on and what steps you have taken so that we can give you a more comprehensive answer.
Please include
Age of your child
age of bullies
# of bullies
specific instances where you felt your child was bullied
How your child reacted
What happened to your child (punishment you indicate from retaliation)
What you did - conversations with teacher/principal etc.
From this point on, I would DOCUMENT - take pictures of online stuff, or communicate with teachers / principal via email.
You are your child's biggest (and, unfortunately, sometimes only advocate). So don't allow yourself to be "pushed aside" if you feel your child REALLY is being bullied.
Good Luck.
