The misuse of alcohol by parents negatively affects the lives and harms the wellbeing of more children than does the misuse of illegal drugs, the report found.
The effects of parents alcohol misuse on children may be hidden for years, whilst children try both to cope with the impact on them, and manage the consequences for their families.
It does not concern only child protection professionals, though alcohol abuse can put children's safety at sustained, serious risk.
The problem affects large numbers of children who never come to the notice of children's social care, the Office of the Children's Commissioner (OCC) has said.
