i used fenugreek when my lo was 6/7 months old because originally i had an oversupply and when i finally got it under control i thought i had an UNDER supply... which was not actually the case. why do you think you need it just curious?
i started with half of what it said on the bottle, and increased until i smelled like maple syrup. everyone says this is when you have the right dosage.
it took 2 or 3 days to notice a difference.
i continued to take it but it ended up bothering my los tummy after a couple weeks so i discontinued use and had no problems with my supply afterward.
nursing often is the best way to up your supply, fyi. plus drink lots of water!
