Abruptly stopped latching- help!

I know everyone says not to quit breastfeeding on your worst day but I’m thinking this isn’t for me. My five week old is constantly fighting latching for the past week. From 4-10 PM she fights every single feed. 80% of the time I quit and give her a bottle of breast milk instead. Luckily this journey hasn’t been hard up until now. Needing support and advice from moms who’ve been through a war seems to me like nursing strike and came back from it.

She doesn’t fight me on all nursing sessions so I don’t think it’s reflux or dairy intolerance. I know around this time is a growth spurt but holy cow I might not make it!

TIA
