I am a first time mother to a 3 week old baby girl who seems to want to be fed every 1 1/2 - 2 hours. While in the hospital she was feeding every 3 - 4 hours but the last week she seems to want more frequent feeds. How do I know if she if actually hungry or just whingy? I try to settle her and end up feeding her when she wont settle. How long should I try settling her before feeding her? Should I try giving her some bottled water in between feeds? Any suggestions would be great!!
