I want, I want, I want, I want

Anna started speaking in sentences recently. It's been very cute, until I realized that all of her sentences start with the words 'I want'. Is this some scary way of showing me what her teenage years are going to be like? Daddy, I want a bmw, Mommy, I want that dress... YIKES! So, far, though it hasn't been so bad. More like, I want food, I want cookie, I want up, I want down, I want Hailey ( although Hailey doesn't want her! ). It's so exciting seeing how Anna is learning!
