Increasing supply

Any tips on increasing supply? I had an oversupply so I stopped pumping to let it regulate to what she needs and then the whole house got RSV and since she wasn’t eating as much my supply dropped drastically. She’s now getting frustrated at the breast (I’m assuming because she’s not getting what she normally does) and I’ve been pumping to try to increase supply but I feel like it just leaves my boobs empty and so when she’s hungry she isn’t getting much out of my breasts and I’m having to give a bottle. WhileI don’t have an issue giving her a bottle if she needs it, I would much rather her eat directly from the boob. I don’t want her getting too used to a bottle because I don’t want her to start preferring it. TIA for any advice!
