Honestly, just nurse regularly and you shouldn't need anything to help with milk. Each time is different. My first son wasn't the greatest breast feeder so I supplemented and gave up breast feeding at 5 months. My second son was a champ. I produced more than enough milk for him and he nursed so long I had to cut him off. :>)))
We have a breastfeeding community on medhelp I highly suggest checking it out, it's awesome:)
I had a mothers breastfeeding tea and the first ingredient was fenugreek, seriously amazing stuff. I made so much milk I was able to donate, good luck!
