Even though childfree & 1-child families are becoming more acceptable, there is STILL UNDERLYING PREJUDICE against such families. Many people still insist that authentic & real families consist of at least 2 children per household. They vehemently contend that childfree & 1-child families aren't really families in the true sense. This attitude is a holdover of pronatalist culture.
Many people believe that marriage should result in children. They opine that couples who willingly don't have children are immature, even self-centered. They maintain that mature married people have children as children are an integral part of marriage. They even assert that being married induces one to have children.
Then there is the issue of the 1-child family. There are people who believe that any couple has purposely have 1 child must be amiss. They strongly argue that children need at least one sibling in order for them to develop properly. They aver that only children are "missing out" because of lack of a sibling. They feel that only children are somewhat misaligned so to speak. They also feel that 1-child families as childfree families are incomplete because there aren't at least 2 children in the family.
On the other hand, people who have lots of children strongly contend that society is prejudiced against large families. They purport feeling out of place in a society which caters to small families. They contend that people look at them as if they were abnormal, wondering why in this age of contraception would anyone elect to have a large family.
Parents who have lots of children routinely remark that there is MORE PREJUDICE against large families than there is against childfree & 1-child families. However, such isn't the case at all.. There IS FAR MORE prejudice against childfree & 1-child families & such prejudice usually comes from parents, especially mothers, of large families.
People really aren't prejudiced against large families. They are rightfully indignant at such families. They criticize such families & rightfully so because such children won't receive the proper parental love & attention. Some children such as the oldest/older children will be cast aside unless they are needed to serve parents & younger siblings. People also know that large families are pathological w/high incidences of abuse, neglect, & diminished opportunities.
