Rebreed Saanen doe?

[longhorngal]

Hi all,
I have a 3 y/o doe that had twin bucklings this year. Her 2nd time around. She had a really hard time with the first one being huge and born with 1 leg back. The second one was smaller but presented completely head first with both legs back! I guess she was so stretched out and he so much smaller that he pretty much just shot out with one push.
However, that whole experience was so traumatic (for me especially!) that I wonder if I should rebreed her or if I do rebreed her to a ND. She was bred to my Lamancha buck this time. I didn't have her for her first pregnancy and know nothing about it.
I guess I'm asking if they have a difficult birth once does that seem to repeat itself or not necessarily?
Thanks
