I have a two+ week-old doeling, one of twins. The mother does not like her, loves her sister though. I started to supplement feed her last week when I decided the mother was not letting her feed, she was a week old (I had seen her nursing during the first few days). What is puzzling me is she isn't very hungry half the time I try to feed her, the other times she feeds good. I see her sneaking up on all the mothers and trying to grab a quick meal. I don't think the mother lets her nurse, have seen her flip the kid over her back once. Should I be worried about feeding her more or just keep on feeding her if she will take the bottle. Not sure what else to do. She is one of my oldest kids but is about half the size of everyone else. Thanks.
