wens,
for my #1, I took fenugeek when he was 4-6 weeks old, cos he seemed to wan milk every 1.5-2 hrs and I tot supply not enuf. I took for 3 days, and duno if it happen to coincide with his colic or even cause it and he was even more cranky.
The side effect for me is my body has a sweet funny smell, even for the BM. Hub ask me to stop taking...
I thk if latching is correct and bb feeding well, the supply will establish in a day or 2. Drk more water/longan red date drk, rest more and ss should be ok.
Try to start pumping early if u thk bb only latch one side to let body know u need extra milk. initially, u wont see much BM gg into the pump.
