Re-Implant XL implants - will I be able to go back to 950 - 1200ccs?

Hello, 12 years ago I had my first BA which was 475cc implants. Five years later I experienced some bottoming out, and decided to increase in size when I had them redone. The second time I had 950cc implants. I had them for almost 6 years but due to child birth/breast feeding I experienced some contracture and had them removed since I was not done having children at the time. Dr Revis did the 950 implants and was excellent. When I had my implants removed I also got a lift since I was left with a lot of extra skin. Now 2 healthy children later I am done having kids, and would like to get my implants back. My question is am I going to start back at square one or would I be able to go back to my 950- 1200s? My long term goal was to get to 1200-1400ccs. My breasts do seem to be more "deflated" as a result of breast feeding 2 children. Im 5'6 and 155lbs.
