When the kid(s) are born, make sure they get attached to a teat as soon as possible after birth and drying. And make sure they're actually getting something out of the teat. The first nursing is colostrum which the sooner baby gets it the better, but really must happen within the first 12 hours or so. Sometimes momma's teats can be "plugged" or really thick colostrum and the kids can't get anything out. Don't "milk momma" before the kids try, as you don't want to waste the colostrum. If you're going to bottle feed, always make sure the kids is warm before feeding. Never feed a cold kid.
