Breastfeeding

For the first 2 weeks, I have been bf my baby and he has been latching well. 3rd week into my confinement we offer mixed feeding (bottle and bf). Last week of confinement till now about 2 weeks I have been exclusively pumping as trying to clear baby jaundice by feeding fm. Now baby jaudice is much better and I tried reintroducing bf however my baby cry when I get him to latch. I cry at the sight that he forget how I bf him. How do I make him latch again?
