In my opinion, any more than 4 children is too many children for a parent to effectively raise. 1-4 is an adequate number of children that parents can effectively raise and give individualized attention to. Parents also have an adequate span of control over that number of children. By span of control, parents can easily raise and manage such children without forcing the oldest/older children to raise the younger siblings.
Small families of 1-2 children offer the best environment in which children can be raised effectively. Children in small families have individualized parental attention. They also have more monies allotted to them which means that there are more monies for intellectual and cultural activities which is missing in large and very large families. In small families, there is an equal parity regarding parental treatment between the oldest and youngest child. In the case of the only child, he/she is corrected as well as praised. In other words, children in small families do not receive preferential treatment.
In 3-4 child families, the medium family, children receive individualized attention although it is a larger sized family. Medium sized families combines siblingship companionship with enough parental attention.Parents still have a span of control over this number of children without the oldest being overburdened, the middle neglected/overlooked and the youngest being spoiled.There is still enough monies allotted in medium sized families for children to have access to the better things of life.
In large and very large families, parental attention is nil or nonexistent.Children oftentimes raise themselves and/or each other.There is very little monies allotted for the necessities, let alone cultural and intellectual activities.There is NO SPAN OF CONTROL in large and very families.Parents DO NOT raise their children, it is THE OLDEST/OLDER CHILDREN who raise the younger siblings thus forfeiting their childhood and adolescence.
In large families, there is AN UNEQUAL parity among the oldest, middle, and youngest children.Oldest children are overburdened and parentified, middle children are ignored, and the youngest children are spoiled rotten and are not given responsibilities. If one hears a person state that HE/SHE loves being in a large familiy, IT IS THE YOUNGEST. There is no such thing as adequate parental attention in large and very large families.BENIGN NEGLECT or worse is typical in the large family environment.
