Re: 5 weeks old bad latch
hi mama, there's really no such thing as foremilk/hindmilk. it's all just milk. the longer the time between feeding, the more fat separates and clings to the milk ducts, and so when you nurse again the milk has less fat until it mixes up again. but all milk is good for your baby and even getting only the early less-fatty milk is RARELY a health concern.
it sounds to me that she's developed this lazy, shallow latch because even with it milk is "pouring" into her mouth, as you say. i think you need to treat the oversupply - by block feeding as PP suggested - and then also start working on her latch, which will be easier when she's not fighting drowning
