Just keep trying she’ll get it again . I had to quit when my daughter was a month old because she had thrush and stopped latching because I was in pain I didn’t mind her not latching so I pumped exclusively. She’s 3 months now and I’ve got her to latch back on 3 weeks ago by just continually putting her on every feed and when shed get upset I give her a binki to calm her down and we’ll try again. I got her to latch again on day 3 and we’ve been doing fine. She can go days without having a bottle with no problem. So just continue to try and put her on every feed at some point she will do it again
