i would push HARD to restrict visitation unless and until he can prove he is sober. he has not done so. on multiple occasions. ALL children are in danger if left in the care of a drunk. or an impaired addict. if you had hired a babysitter and came home to find this babysitter passed OUT on the couch while your precious children are left unattended.....what would you do?
HE is no different, regardless of his tag of "father" - fathers should not keep their children home because they are too drunk or too hungover to get their children to SCHOOL.
