That's why I had one. I breast fed Kai and my quite ample chest just disappeared after I stopped breast feeding. I was gutted and I wasn't happy with my body at all, I just didn't feel in proportion.

To be honest it's the best thing that I ever did. I love my boobs and if they ever headed south again I wouldn't hesitate to get them done again. My surgeon told me if I had another baby that I should wear a bra throughout my pregnancy to make sure that they didn't sag and that's exactly what I did

To be honest from the pictures I've seen of your Mrs I wouldn't say that she needs a boob job, she looks fine as she is
