My state mandates an almost 50/50 split of time, and the custody laws don't protect children from spending a great deal with an alcoholic unless the alcoholic harms them.
I do worry every time a long visit comes up (as with Thanksgiving) and wish courts and legislatures could see the long-term damage they do by forcing children to spend so much time with a parent who is unstable, unhealthy, and unloving.
Thanks for starting this thread. I pray for safety and comfort of all our children and stable parents this week.
