Early in the play, the Nurse is a bit stuck in the past, treating Juliet like the little baby she helped raise and telling embarrassing stories.
Later, she first is more adult, about marriage, and then a bit crude, dropping jokes in.
When Tybalt is killed, the Nurse judges Juliet pretty harshly.
However, throughout the play, the Nurse wants to help and protect Juliet, and loves her. That does not change.
