RE: "Back Fat"
>1. Will I ever go back to my pre-pregnancy bra size?
Depends. Some women don't, some do and some go down to a smaller size.
>2. Will the "back fat" go down the same time with my chest
>after I wean?
I don't know. Since you are only 5 pounds up from your pre-baby size it might all be around your breasts. Weight training could help tone that area, causing you to lose inches but not weight.
>3. Is it true that until you wean, your body (particularly
>the back/chest area) will retain fat to help with
>breastfeeding?
Yes, this happens for a lot of women. I shed a bunch of weight once we stopped nursing.
