5. Living at home for too long stagnates the child’s personal development.

Many young adults in their mid-20s and early 30s, and especially men, are increasingly postponing the transition to adulthood. Rather than the 'empty nest' we often now have the 'never empty nest' and some of the recent ways to describe these young adults are 'fledgling', 'incompletely launched', 'near adult' etc. Even though they are chronological adults, emotionally they are children or adolescents. They prefer to remain in the psychological comforting womb of living and otherwise being financially dependent upon their parents although they are capable of obtaining a job and living on their own.

Pulling their own weight in the household is not enough to make them feel like adults. Even when they do finally leave the nest, the twenty- and thirtysomethings are still postponing the moment of settling down with a significant other. This is borne out by the fact that the average age for forming a stable partnership and having children is rising among more affluent young adults.

6. Living with parents, young adults may gain complexes and wrong behavioral patterns.

Many adult children of overprotective and overindulgent parents develop risk aversive behavior. They do not have the prerequisite life skills needed to become totally self-sufficient. They believe that life should always be easy and crumble, when life presents its more negative aspects. They often refuse to realize that often adverse situations make them more resolute and resilient.

Some young adults are quite fearful of being totally independent because they have a fear of failure. They believe that life must be perfect and that there should be no rejections and failures. The process of ever evolving adulthood is often filled with small steps. In other words, one must metaphorically crawl before he/she can walk. And rejections and failures are parts of the life process and there is no escaping this! Experiencing rejections and failures makes a person more mature and aware as to not what to do the next time. Furthermore, rejections and failures are learning and growth experiences. Success often comes with rejections and failures. Many people fail to realize this.

Moreover, there are young adults who have an entitlement mentality. They believe that they should never have to struggle in life and that everything should be handed to them without any effort on their part. They want the nice job now. They want to earn a lot of money now. They want the nice apartment now. Yes, there are some young adults who by their own efforts have a great job, earn a high salary, and have nice apartments, even nice houses. However, the average young adult starting out often must endure socioeconomic struggles for awhile before he/she is in a comfortable status. There are many young adults who prefer to depend on their parents and live comfortably than to live somewhat uncomfortably on their own. They fail to realize their parents had to struggle and make sacrifices to reach their present socioeconomic level.

7. In case of staying in the nest, the child can lose independence.

If you move out to live by yourself you do what you want to do, but if you stay you will have to abide by your parents’ rules. You might find your wings clipped and not be allowed to do some things in your parents’ house. Another negative point is that people may look at you differently because you are a grown up and still living with your parents. At the same time parents often find it quite challenging to admit you’re not a baby anymore and to be on an equal footing. What is more, a great number of parents believe that since you live under their roof, they have a final say in all the discussions and decisions taken.

8. Letting your children is every parent’s duty.

Children need a pinch of risk as much as vitamins. Children need to become independent decision-makers who learn from their own mistakes and failures.  So to let them go is another parents’ duty, just like to provide them with education or food. An overprotected child is a deprived one and if they find themselves in an arrested stage of development they should make a claim for psychological abuse.

The parents' work and dedication to the success of their children" is time-consuming and exhausting. Making things run smoothly has become ingrained in the parents' relationship with their child. However, chronological age outdistances parents' ability to keep up with all that is going on with their child. This is the conflict. Parents are doing things to assure success for their child. This encourages the child to become dependent upon their parents for their achievements.

Many times the work parents have done has fostered dependence, not independence. Parents are caught in a time bind. They are doing what is necessary to allow their children to be successful, but that very work inhibits the child's success once they leave home.

In a nutshell, parents must learn to do less for their young adults and cut them off in due time.

9. When living with parents, it may become too crowded.

Sharing the family home requires adjustments for all. There are the hassles over bathrooms, telephones and privacy. The situation may become absurd, like each having a scheduled shower time. Everyone is to try to act like everything's fine, but the pressure can build until there's an outward explosion. It's not that you don't love each other, it's just that it's hard for parents to have their well-earned space invaded by other family members. Many families fail, however, to manage the delicate balancing act.

10. Constant conflicts might provoke violence.

Teenagers lashing out at their parents is the most secret domestic violence of all. But it does happen, probably a lot more often than we think. This violence might be physical, emotional or financial.

Mums are more often on the receiving end than dads. And while plenty of us know we'd never tolerate violence in a partner, it's suddenly very different when the male-on-female violence in the house emanates not from your partner, but from your son.

11. Staying in the nest is disappointing for your parents.

The job of parents are raising children with the ultimate purpose of making them independent adults, emotionally, intellectually, and financially. It is the job of children to become increasing autonomous as to achieve that goal. In fact, both parents and children anticipate the latter's independence as adults. Parents know that by having an adult child who can take care of himself/herself, they were successful parents. Some of the feelings one may have when young adult stays at home for too long may include disappointment, resentment, anger, guilt, feelings of loss of privacy and increased stress on financial resources.

What is more, aging parents, who should be enjoying some financial and personal freedom, find themselves bogged down again with responsibilities.

12. Staying at home means postponing your marriage.

One possible side effect of the parasite single phenomenon is the increase of the average age of the first marriage (though this is also attributable to other factors like career prospects and education). While in 1970 women married on average at age 24 and men at age 27, this has increased to 27.4 years for women and 29 years for men in 2002. This has also resulted in women having children later in life, and fewer children overall due to the decline in fertility after age 30.
