With respect, i am fully aware of how to breed successfully and responsibly in younger rabbits, and it is because I am aware that her age may be against her that I have asked such an emotive question on this site. As explained, I have no intention of doing anything that may harm her or any kits should she become pregnant. My animals are more important to me than my husband or any other person I know, so i do resent the implication that I would not "do it properly" or have my animals best interest at heart.
With respect, there was nothing in your original post to indicate any sort of knowledge, so I responding purely to your first post, and nothing else. The question was about a first time mum at 2 and a half, and that question was enough to ring alarm bells.
It's great how much you love your bunnies and that you keep them all and also that you don't want to do anything that may risk her, so for the sake of this girlie, in this instance I would avoid breeding her.
