As her mother, Lady Capulet should know everything that there is about her daughter; she should know how old she is and her innermost feelings. However, Lady Capulet knows neither. Early on in Act 1, Lady Capulet is unsure of Juliet's age and the Nurse has an extended speech in which she explains to Juliet's mother how she knows how old Juliet is better than her mother does. Additionally, throughout the play, it is the Nurse that Juliet goes to for advice and assistance, not her mother.
