Products to boost lactation/milk supply

hey mommas!

I'm pregnant with my 2nd, breast feeding didnt go as well as I would have liked the 1st time around. I had a low milk supply (like .5-1oz per breast per session) and latch issues (which required the annoying nipple shields). I had tried power pumping, flax seed, fenugreek, brewers yeast, oatmeal...

So I'm trying to be proactive and prepared this time.

Is there any alternative to nipple shields or specific brand shields that seemed to work best for you and your baby?

Are there any lactation products that worked for you (milkflow, ect)?

Are there any lactation recipes or supplements you swear by?

Anyone have their milk supply be great the 2nd time after a disappointing prior experience?
