Sigh... NO. That is just ridiculous.
There is no way to magically get larger breasts with pills, certain foods, or even running down the street nude. The only ways to get larger breasts are to either get cosmetic surgery, gain weight, or get pregnant. However, these are not really recommended.
The most you can do without doing any of that is just make them appear larger. If you are interested in making your breasts appear larger, check out my how to "How To Get Larger Breasts!" - http://www.funadvice.com/howto/larger_breasts
no, laying on your stomatch has no effect on the size of your boobs or how they develop.. it does not decrease or increase fat
the way your breasts are, is determined by your genes. So, if you sleep on your stomach, you'll be fine :)
No, it will not get any smaller or bigger. Trust me.
