And I also don't get your hurry to get her pregnant again. If you put dad back in, she will get pregnant. Why are you in such a hurry to get babies?
I think you are mistaking her want for dad and mom not to become unfamiliar with each other for wanting babies quickly. If she wanted the babies so badly...she wouldn't have taken the initial advice she had gotten about breedbacks and kept them apart for the first week.
I know we are all too familiar with inexperienced breeders just wanting cute babies, but before jumping on her you should ask for clarification like volunteer did.
That aside, Grace, don't worry about them not getting along again. When mom has kits with her, she will be less likely to accept her mate back because she will want to protect her babies. I would keep dad out for the entire time she is nursing. Just give her the time to raise the baby without having to worry about being mated. If they got along well before the baby the chances of them getting along again are fairly high.
