Not necessarily. I wouldn't let them have the child if their episode occurred in their contact time. They do need to tackle their drinking, though.
I suppose from the view of the officals (Child Family Services or whomever works these kinds of committees) you probably do pose a risk. No matter what the story may be, and weather it happens with the kids around or not, they will never see it as anything beyond "potential to be a problem" those "people" are just that way.
No....just sounds like an occasional drunken night.
but if he's not there...how is that a risk?
If you are not together though...the law and even morality doesn't usually work that way. I'm not saying it's good.....but he isn't required to remain sober when not responsible for caring for the children.
