Exclusively pumping questions

1. I wash my pump parts once per day, and then otherwise store them in the fridge between pumps. Is this ok?

2. My baby is 5 days old. I pump 30 minutes before she eats every 3 hours. I get about 2 oz a pump, which is how much she drinks. Is this a good supply or too little?

I think that’s it for now but if anyone has any advice or tips for exclusively pumping I’d love to know.

My baby hates the breast and before you ask no it’s not her latch, my boobs are 42J and a lot of surface area for her tiny mouth. I still try to get her to breastfeed periodically but it stresses us both out so for now I’m not pushing the issue. She is getting plenty to eat. Thanks mamas.
