Baby rabbits drink their mother's milk, i.e. rabbit milk. If the baby rabbit is domestic and orphaned, you can try feeding it Kitten Milk Replacer (KRM); if the rabbit is wild, use goat milk. However, it can be very, very difficult to hand-raise rabbits, especially if you aren't experienced. If you find yourself in charge of an orphaned baby rabbit, do lots of research and contact local experts in your area. See the related link below for a place to start.
