Baby rabbits should only be fed once a day. Sometimes twice but no more than that. Babies usually feed on their backs. You can try this by laying them on a cloth in the nook for your arm or even in your lap. Baby rabbits should be fed a Kitten Milk Replacer. Also, you should add a tablespoon of cream because rabbit milk is extremely high in calories. You should feed the rabbits using an eyedropper and give about 5cc’s of milk replacer as a newborn and double it every week until weaned. They should usually be weaned around 4 weeks.
