Girls are more vocal than boys, and sanguines are more vocal than any of the other temperaments (which are 'phlegmatics', 'cholerics', and 'melancholies', & 'supines' -- in case you want to look them up). I am a sanguine, myself, so I know (and all those around me do, too -- and have for almost 53 years, now ; ) I'd say this is the deal with your daughter. She'll probably need lots of praise and affirmation to keep her bouyed up throughout her life. Criticism will deflate and deject her (I also know this from experience).
(P.S. My kids [now 22, 24, 30, & 33) always loved making noise in a big public bathroom where everything echoed. LOL)
