Wauhhh....i do agree with you.
Moreover, some of these cases may not appear in some region. In africa(home), it is hard to find a family with just a father, mother and children. In most cases, the family is parked with family members such as uncles, aunts, cousins and others.
I would say that this has advantages and disadvantages on children since they can't enjoy their time with the parents. It makes children not friendly to the parents and become more friendly to other people who may teach them the wrong or right things.
I would appreciate such a family as yours if the parents take their responsibility. This can lead to a somehow perfect growth of the children.
In conclusion, I may say that for a child to grow perfectly, it all depends on his environment. Whether he stays near the parents or with the large family, what maters is the environment.
Just my opinion and not contradiction.
Thank you again.
