If so, at what age. We have 2 kids that are almost 2 weeks old. Sometimes when they run up and try to nurse, their mother walks away and doesn't let them. At other times I have seen her just stand there and let them nurse. She is a very good mom, so I was just wondering if she was "limiting" their nursing time and maybe working up to when they would be weaned. They are already nibblling at and eating hay and grain.
