The Domestic Abuse Act is clear that children are also victims of domestic abuse and this can be from witnessing abuse.  From this page you can download leaflets about supporting a child who has experienced domestic abuse.  The set of ten leaflets cover ages from baby to teenager and other related topics. 
These leaflets were reproduced for Cambridgeshire from the originals with kind permission of West Mercia Women's Aid
