Baby not gaining weight!

Jennifer
I feel somewhat like a failure at the moment. My beautiful daughter is now two weeks old, and hasn't gained an ounce since coming home from the hospital. She's being fed every hour and a holds to two hours as she's ready, she's getting plenty of diapers and she's grown an inch since birth... doctor says color and everything else seems fine, but she's just not gaining. It's kind of freaking me out. My supply is fine, and I'm not only staying hydrated, but I'm also getting oatmeal in my diet daily. Any mommys with suggestions??
