Hard time breastfeeding in public

It’s not me that has a hard time in public.. it’s my little one? She does great at home but I mostly lay her down to nurse her because I’m so big chested and it’s just easier to lay her down. She literally HATES nursing when we’re out and about.. she will get fussy and arch her back when I try to latch her.. I feel like kind of my boob is overwhelming I’m sure at times. But it also gives me anxiety if I need to go anywhere.. any ideas? I don’t know if she associates boob with bed? And she thinks I’m trying to make her go to sleep which she don’t want to? She refuses the boob almost. But if I try to give her baby food, etc.. she opens right up. Any ideas?
