36 Years Old, 5'4" 125 Pounds, 34A, Hoping for a Full C/small D

Let me first start by saying I LOVE my body! It's grown 6 beautiful and amazing children and breastfed each and every one of them anywhere from 13 months to 2.5 years. I just did a gentle wean with my last baby who is now 20 months old. I exercise regularly but don't obsess, just try to stay active with my kids. I work part-time and I'm enrolled in school part-time (currently) and plan on becoming a full-time student in a couple years.
My breasts have always been small, but perky, like most of you I'm sure. When breastfeeding they were as big as a D in the first few months then leveled out to a nice full B. I'm amazed at how much volume is now gone. I've thought about a breast augmentation since the birth of number 4. I don't think I would ever have had the courage to do it until a close friend of mine had hers done back in November.
I met with my PS back in January and called to schedule the surgery a week later. I waited until June so I could breastfeed a little longer and so my husband could be home with me for a longer period of time after the surgery. When I met with my surgeon I had not done ANY research. He suggested round, high profile 300cc silicone. I've e-mailed him a few times since the consult and have decided I'm more comfortable with saline and possibly doing 350-400cc but nothing is final yet. I have my pre-op appt on May 27 and I'm hoping to try on the sizers again and see what his recommendation is for me. I'm also really worried about high profile, I do NOT want a lot of projection but I do want fullness and that nice slope natural breasts have. I mean I'm 36 not 18! I want to look like a woman that had 6 kids, if that makes any sense.
Anyway, I'll hopefully get the courage to post some pictures in the next couple weeks :)

I'm going to start adding wish pics. I wasn't totally sure how to do it. So I'll add the pics with a caption thanking the realself member!

I definitely never thought I would be at this point. Some weeks felt like forever!! I've read a lot of posts about women being a month out and they seemed more prepared than me. Is there something I should be doing? No clue. Just waiting for my preop appt to go over everything with my PS for the last time. I'm not as concerned with size as I was when I first started researching. I think 325-375cc will be perfect. I am worried about profile! He suggested high profile but I don't want a ton of upper pole. Attaching my original wish pic, wish she posted more results!!
