To add on to what the other moms are recommending , breast feeding at night is best than the day as well because your prolactin levels are higher at night and help build and maintain your supply. 

Be cautious with fenugreek! I was using Milkflow drinks and mother's milk tea and it had the opposite effect on me and dried me up! My lac consultant told me to stop immediately and since then it's been a battle to get back to where I was. 😳

Why do you think your milk is drying up? Is it because baby is feeding more often? If so baby could be cluster feeding. This is for a growth spurt and to help increase your supply. Drink a glass of water as each feedings and eat 3 meals and snacks throughout the day

I heard oatmeal in the mornings works great I don't know if it worked for me or just the power of suggestion but I'd say give it a try along with lots of water.

Express in between feeds and try to feed more frequently 

Dealing with low supply too. Fenugreek 3 pills 3x daily. I also take Alfalfa (2 grams daily) and Shatavari (2400mg daily). Nursing tea with Goat's rue also once daily to help grow breast tissue. Tons of water, 6 hours of sleep at night and I take naps on weekends. This has helped tremendously. Another key thing is to lower stress levels, and be sure to pump once between 1am and 5am. Also if you can manage to find any, Torbangun is supposed to be a very powerful herb but it is extremely rare to find

Take fenugreek pills 3 times a day 

How often are you breastfeeding the baby? 

Pump!!! Feed the baby switching sides every time. If you think you're drinking enough water, drink more!!! Eat lots of fruits and veggies they have water content in them. 

Combo of feeding from the breast, and pumping... I pump after feeds to get more out..
