So - at 6 mos preggo my bra's are finally not doing the job. I was fairly gifted in the chest department (34-36C/D) pre preg so I know I am likely going to end up in a F or G while nursing. There is a store near my house having a big sale on nursing Bra's (Medela seamless softcup and underwire nursing bra's) both $24/each. I am thinking when I invest in new bra's now I might as well invest in nursing Bra's. Is there any reason I shouldnt do this? Is there anything about a nursing bra that would prohibit me from using them now?

Thanks for any input you may have!
