I have a cria, 12 days old. Mom never let him nurse, we tried leaving alone, nothing. We've been bottle feeding, and I'm not sure what type of schedule to use. Right now we're feeding every 2 hours and he takes from 2 - 6 ounces (usually more from me than my son). How often and how much should we be feeding? How do we know when to increase time between feedings? Any advice is welcome.
