newborn wont stop eating

my baby turns 2 weeks old tommorow and she won't stop eating. she's eating about 4 ounces every hour. I just have her 3 ounces and she was still fuzzy and hungry so I have her another 1 and a half. and she's still upset and wants more. what do I do?! is this normal?! she doesn't spit up any and keeps it all down just wants ALOT
