Nipple Confusion

Just given birth on 5 Jan and baby having jaundice due to insufficient feeding as my breast milk only kick in after day 4. Due to this, I to try pump and top up with formula and bottle feed. But now the issue is after bottle feed for a few days, my little one seems to experience nipple Confusion. She will cry and get frustrated when I try latch her on. I am so sad that she can't seem to switch over from bottle to my latch on. What can I do. If insufficient feed, I worry the jaundice will not clear fast.
