FTM, have I failed?😩

My baby was in nicu 3 days after she was born and my milk came in late so they fed her formula using a cup.

She’s 9 days old, now prefers to use a bottle to feeding on my breast. I always thought i would do strictly breastmilk but i am beginning to think maybe i can’t.

My nipples are not pronounced so we probably have a latch problem, she just cries and struggles on my breast.

Can i still make her prefer breastfeeding or am i too late and have to stick to bottle feeding (pumping is serious work)? How can i achieve this?

Please help! Thank you
