36 Years Old, Momma of Two Breast Fed for over a Year Each, Totally Deflated Small A's - SC

Like so many others, I have talked about this for so long. Even before kids I was the smallest chested out of all of my friends. This didn't bother me so much because they were cute and perky and didn't limit what I could wear. Depending on where I purchased my bra I was between a 32B and 32C - bigger B much smaller C. After having my sons and breast feeding they just lost all form. They have so little volume in them that my nipples have lost all form and sink down and in. I really don't even like my husband to see them. I am a very confident person - I am in sales which kinda requires a certain level of confidence in yourself. But this is just something I haven't been able to get over. I am in great shape and exercise regularly. I am 5'5" 120lbs. My husband after our first son was completely against this idea, but after our second and seeing how happy I was again when I was nursing our baby and had breasts again he gave me the thumbs up. Not that I 'needed his permission' but let's face it - it's not cheap so to have him not feeling great about it would definitely make it hard for me to move forward with it. Not to mention I will be slightly out of commission and unable to hold our youngest for a little while.
So this is where I am now. I am meeting with three different providers in my area at the end of May/beginning of June and will make my decision after that.

Deflated

I met with two doctors and just knew it was right with the second meeting so cancelled the appointment with the third. I'm aiming for 275-300 cc cohesive gel under the muscle. I'm scared to be too big but I'm also scared to wish I would've gone bigger. My surgery is September 5th so I have time to think about it. Any opinions?
