Example 3: A parent that throws their 15 year old kid out of the house
WT doesn't ask parents to throw their minor kids out of their house:
Thereafter, what would parents do in behalf of their erring minor child? They are still responsible for their child, though he is disqualified as an unbaptized publisher or even if he is disfellowshipped because of wrongdoing after baptism. Just as they will continue to provide him with food, clothing, and shelter, they need to instruct and discipline him in line with God’s Word."- W88 11/15
If a minor child living in the home is disfellowshipped, Christian parents are still responsible for his upbringing.Loving parents may thus arrange to have a home Bible study with him, even if he is disfellowshipped. Maybe he will derive the most corrective benefit from their studying with him alone. Or they may decide that he can continue to share in the family study arrangement.” - km 8/02
In some instances, the disfellowshipped family member may still be living in the same home as part of the immediate household...Since his being disfellowshipped does not sever the family ties, normal day-to-day family activities and dealings may continue. - lv 207-209
