Am pg with DC1 and will definitely be giving BF'ing a go. However I want to be prepared and I can't get any info about the negative effects of BF'ing on your body long-term/permanently (e.g. saggy breasts), only the temporary stuff. Sorry if this sounds really vain, I know it does 
I am hoping for honest answers from ladies who have been there done that, and perhaps any tips for limiting the situation. Many thanks.
