Yep, the Nurse is like a real mother to her and her closest adviser.
Juliet is close to her nurse because while her mother occupies herself with her duties with Lord Capulet, the nurse acts as Juliet's actual mother. In other words, the nurse is Juliet's caretaker. I can't believe I just did your homework for you.... ;)
The Nurse and Friar Lawrence knew about it before anyone else because the Friar performed the marriage and the Nurse was Juliet's close confidant so she told her everything.
Juliet was likely looked after by a nurse or a caregiver as a child. In Shakespeare's play "Romeo and Juliet," her nurse is a prominent character who has a close relationship with Juliet and helps to care for her.
In "Romeo and Juliet," Susan is a character referenced by the Nurse when she talks about Juliet as a baby. Susan was Juliet's nursemaid who breastfed her as a baby, but she died when Juliet was young. Susan's name serves to show the close bond between Juliet and the Nurse.
The nurse seems worried in Romeo and Juliet when she learns of Juliet's secret relationship with Romeo because she knows the implications of their families' feuds. She also worries about Juliet's well-being and the consequences of their forbidden love.
The nurse remembers the exact hour of Juliet's birth because she has been with Juliet since she was a baby and has a close and nurturing relationship with her. It's a detail that the nurse holds onto as a sign of her devotion and care for Juliet.
Lady Capulet is Juliets mother BUT the nurse brought Juliet up. Juliet was raised in Italy in the house of Lord and Lady Capulet, her parents. But largely by her Nurse and servant Angelica.
The Nurse. :)
The nurse seems to be supportive and excited about the marriage in Romeo and Juliet Act 2, Scene 5. She is happy to be helping Juliet and Romeo arrange their secret marriage and wishes them well.
They both learn their respective identities from the nurse: Romeo first, then Juliet.
Juliet's nurse.
Juliet's relationship with her nurse has changed from being close and open to being secretive and distant. Juliet can no longer confide in her nurse about her feelings for Romeo, as she must keep her love a secret from her family. Their relationship has grown strained due to Juliet's desire to marry Romeo against her family's wishes.
