How to latch?

Maria

My baby 3weeks old , and is bottle feed , I pump and bottle feed and it's honestly so exhausting when I have to pump and she's crying . I want to try to get her to go on my nipple , is it to late to get her to latch on nipple if so how can I get her to latch? , Is it patience? What can I do, is it to late? Bc when I do try she cry's and I give up and just give her the bottle
