According to the National Association for Children's Alcoholics (NACO), there are 2.6 million children living with alcohol addicts in the United Kingdom.
A charitable organization that advises and supports children of alcoholics says that last year the number of requests for help increased by more than 20,000 calls.
Despite these figures, this question is still mostly invisible, as many children do not want or can not get the help they need, which leads to questions that can last for a long time in their adult life.
A charity organization says alcoholics children are six times more likely to witness domestic violence, three times more likely to deal with suicide, and twice as likely to have problems at school.
Nacoa Ambassador Josh Connolly told Sky News: "For young people who may be struggling with a parent who drinks too much, we want to say" you are not alone in your own battles and you are justified as you feel "… and that t help and support.
Nacoa celebrates a week of children's alcoholic beverages, an international campaign to raise awareness about millions of children affected by drinking their parents.
Some sponsors of the campaign shared their experiences in order to "clear the conspiracy of silence" around the children of heavy drinkers.
Jonathan Ashworth, Secretary of Shadow Health, said: "I am happy to support and associate with the week of the child of alcoholic beverages.
"Two years ago I was inspired by friends like Liam Byrne and Caroline Flint to speak publicly in a parliamentary debate about my own circumstances of growing up with my father's alcoholics. Since then, I have been a passionate advocate. This cause helps the government allocate some funds to helping children of alcoholics.
Arsenal and English football star Tony Adams said: "As an alcoholic who remembers, I know how to hit the bottom and survive, and places that understand and will help and support you."
Calum Best, the television star and son of the football legend George Best, told Sky News: "My father was very drunk … for every good time I had with my father, it was always a bad time to be sad overshadowed by the drinking involved. "
He added: "You try to find out all the things with an alcoholic parent, and the answers are limited."
