I'v been crying cause Idk what to do is it normal that I feed her for 30 mins then give her 2oz in the bottle and she is still hungry?

That's what newborns do when they are breastfed. They are literally attached to you. It's called cluster feeding. It's the hardest part of breastfeeding because you literally sit there with a baby attached to your chest. And don't be upset that you only get an ounce of milk, that happens for most of us. It has nothing to do with the amount of milk your baby is getting. If you want to produce more milk while pumping you have to pump more. It tells your brain to tell your breasts that there is a demand for milk and they need to meet that demand.
