My baby won't latch 😔

LJ • Baby girl born Feb 19, 2015 and second girl born Jan 20, 2017. Baby #3 due in October!
She is almost two weeks old now and will only eat out of a bottle. We spent two days in the hospital where she would latch with a nipple shield. Two days at home same thing, then got sent to the NICU for 5 days for jaundice. Mostly bottle feeding then with a few attempts at breastfeeding. Since coming come, she just doesn't have any interest in feeding from me. I do pump so she is getting mainly breast milk and getting some formula to supplement when she is still hungry. Any suggestions as to how to get her to breastfeed again?
