OPINIONS!!

So my daughter is breastfeed but I pump my supply is starting to get low I’ve been trying everything to get it back up but nothing is working ! She is also very picky with her milk she won’t drink the frozen milk at all I’ve tried multiple times morning night during the day nothing ! So my frozen stash is out of the question sadly ! So my question is should I should stop pumping and give her formula which I have tried a few times and she refused it but should I just keep giving it to her until she takes it but she might starve herself before she ends up taking it :( ? Just looking for some

opinions or if this has happened before to your little one? Thanks :)
