Saline-Implants

Breast Implants: Saline or Silicone and Why?

So doing some research and am considering breast augmentation. I would like to hear your opinion/personal experience and whether it was good or bad. Thanks!!
I am getting them because I am currently a A almost a AA cup. I am pettite 5′1" and 105 pounds, however I have had 3 children and they are just not what they used to be. I am not looking to go huge I just want a little something!
