She is one of the few people, along with Friar Laurence, to be made aware of the blossoming romance between Romeo and Juliet.

The Nurse is a character in Arthur Brooke's poem The Tragical History of Romeus and Juliet, as Shakespeare's main source text.

The Nurse plays a similar role in the poem by Brooke, though she is less critical of Paris and is banished for the events that took place.

[1] The Nurse is sent by Juliet in act two, scene four to seek out Romeo the night after their first kiss and exchange of vows.

When Juliet learns that her parents expect her to marry Paris, the Nurse urges the girl to go ahead with the marriage.

The Nurse discovers Juliet under the spell of Friar Laurence's potion in act four, scene five, and the grief of her death as seriously as she mourned Tybalt.

Indeed, she loses perhaps the dearest friends of anyone, having suffered through the deaths of her husband, Susan, Tybalt, Romeo, and Juliet.

[4] Friar Laurence agrees to marry Romeo to Juliet in an attempt to mend the dispute between the two families; the Nurse sees their union as one of legitimate romance.

The formal language Juliet uses around Paris, as well as the way she talks about him to her Nurse, show that her feelings clearly lie with Romeo.
