The baby gains more independence and has formed several attachments at this point. A majority of infants have formed multiple attachments by 18 months of age. Studies show that attachments do not form with the person they spend more time with, rather with the person who responds more accurately to the baby’s signals. When forming attachments, playing and communicating with a child is more important than feeding and changing the child which shows that responsiveness is the key to forming healthy attachments.
