not a barker, not a howler!

Hello Husky lovers....

I just got my blue eyed princess 2 months ago and to my surprise she does not bark nor howl! She screams whenever we bathe her and whenever she gets stuck somewhere, so I know she has a voice, but we have NEVER in those 2 mongths heard her make any other sound. She is about 4-5 months old... Im just wondering... is this normal? What should i do!!
