After 3 years of boys, what's it like finally having a girl?

Question ladies, after being around boys for 3 years, my son and two nephews, how is it finally having a girl? My niece is due any day now and we'll I guess I'm asking did y'alls little girls turn out to hell raisers or little princesses? My sister is anxious as to how things will go. I know it's all different but how did it turn out?
