1) talk to children candidly about the effect of alcohol and the precautions that they must taken when exposed to it with the other parent;
2) obtaining an explicit court order that specifies the conditions under which the other parent will have access to the children;
3) consider sending the children for therapy if they have been exposed to alcoholic abuse first hand;
4) be mindful of the children’s needs and answer any questions or concerns they may have.
