1 month old won't eat/ stay asleep

Kat

It's becoming very frustrating. I know she's hungry, she knows she's hungry. I give her the bottle and all she does is like, bite on the nipple. Doesn't suck. When she does eat she will eat a ounce or two then only sleep for less than a hour. What she used to do was eat 4 ounces of milk with no problem, pass out, and wake up 3 hours later or so. And when she actually does eat she flails her arms around, kicks, whines, grunts.

What am I doing wrong? I feel like all I'm doing all day is feeding her. I believe this is called cluster feeding. I don't have time to do anything I need to do. I need to shower, clean the house up, do laundry.. SLEEP. Going crazy here. Help.
