It may not be done perfectly, but it's done. Once it is done, however, don't go over the child's efforts. The child will get the idea he or she can't do anything right and may, in turn, strive for perfection to gain acceptance. Let them do the tasks their way sometimes. Recognize that parents aren't instantly equipped with parental love and caring skills.
Most jobs require a training period.
Parenthood is no exception, but the training usually is done on the job and lasts a lifetime. It takes time, patience and experience to build a positive parent-child relationship. Since growing children are constantly changing, perfecting a particular parenting skill is almost impossible. Develop a sense of humor. Perfectionists tend to take themselves, their children, their work too seriously.
