I am 24 and have had 2 kids. For the most part I look and feel 18, except when I look in the mirror after I get out of the shower. My chest looks like my mother. I would really like breast implants or something to fill up and pull up my breasts, but i'm not thrilled about the idea of going under the knife for something that only bothers me. Is there an exercise that I could do to fix this problem?
