She is definitely not her brother. With Xavier, when he has a loose tooth, he'll work at it as soon as it's a tiny bit loose and have that sucker out by the end of the day. Leia patiently waited for the big tooth to come in and gently push the baby tooth out! She also wants "the tooth fairy to leave a prize all wrapped up with a bow under her pillow".
*sigh* So much for just throwing a dollar under her pillow! Women!!!! ;-)
