If the child has had a peaceful gestation, but after birth suffers pain or ungratified needs during the first year, attachment will again be blocked. If the child reaches the toddler period safely, but is not treated with strict authority during the second year, according to the so-called "attachment cycle", attachment problems will result. Failure of attachment results in a lengthy list of mood and behavior problems, but these may not be revealed until the child is much older. According to attachment therapist Elizabeth Randolph, attachment problems can be diagnosed even in an asymptomatic child through observation of the child's inability to crawl backward on command.
