Gender Reveal

We are currently pregnant with baby #5!! My daughter is 16, followed by three sons, age 10, 5 and 6 months. We wanted the last two close in age. We never had any baby showers after the first baby, despite the age gaps....just feel like it's supposed to be that way..... But...with this last baby, we'd like my oldest daughter to be the only one to know the gender and we'll have a gender reveal party to see if she'll be the only princess, or if we'll finish with a girl. Either way we'll be over the moon, just thought it would be a fun way to end the building of our family. Think it's appropriate? I'm not in it for gifts, I just want to share our elation with family.
