To many parents, the youngest child is their baby, their jewel. Also, the youngest child in the family is the parents' LAST child- there WILL be NO MORE after him/her. Parents also view the youngest child as more fragile and in need of their love and protection regardless of the age of the youngest child.
In addition to that, parents are more relaxed and experienced when the youngest child arrives. They are likely to be more lax regarding this child than they were their older children. As a result of this parental experience, youngest children are more likely to get away with things that their older counterparts were often disciplined and/or chastised for.
Youngest children know this and often use this for their advantage. Because they are the youngest, they are considered to be "not knowing any better." In many families, older children are oftentimes punished for the things the youngest child does because it is the parents' belief that the youngest as the baby is wholly innocent of any wrongdoing.
Youngest children are known as the cute ones in the family. They realize this and are often the attention grabbers and stars of the family. Parents and older siblings adore them and want to do everything possible to please and placate the baby of the family. Many youngest children are treated as princes and princesses in their family with their every need catered to.
In contrast to their older, particularly the oldest siblings, youngest children have the longest and freest childhoods and adolescence; oftentimes into early adulthood. In addition to that, they have the LEAST familial responsibilities of all birth orders. Yes, youngest children have IT MADE in the shade so to speak.
Family size is highly influential as to the amount of spoilage regarding the youngest child. In small and medium sized families (2-4 children per household), youngest children are more or less on an equal parity with their older siblings. In such families, what goes for one oftentimes goes for all. However, in medium large to very large families(5 and more children per household), youngest children are more likely to be spoiled and coddled while the older children bear the brunt of the familial responsibilities and the parental discipline. Also in medium large to very large families, it is the youngest child who has the MOST and ADVANTAGEOUS educational and socioeconomic opportunities.
