I feed newborns 5 times a day, for atleast the first week (but usually atleast 2 weeks), then they are on 4 a day til they are atleast 8 weeks, when they can be moved down to 3. And I'd never wean bottle babies before 10 weeks (I wean dam raised sale kids 10-12 weeks, as early as 8 weeks if it's a buck (and acting that way), longer if it's a keeper doe), generally my bottle babies are on the bottle til they start acting ready to wean, which can be 12 weeks on, but generally by 4 months. It won't hurt them to start weaning at 10 weeks, that's just how I do it.
