A mommy makeover is a complex operation. To get good results with the least possibility of complications you need to consider that there are a great many expensive hidden costs that are bundled into the fee you are paying. Remember too, that a mommy makeover includes the cost of your tummy tuck as well as a breast procedure; either a breast augmentation or breast lift or breast reduction depending upon your needs.
I encourage you to keep saving and make sure that you see a surgeon completely certified to do your surgery.
