EPers, how do you increase supply during a growth spurt?

My DD is going through a growth spurt and we actually had to supplement with formula last night bc she was still so hungry. I cried. I was caught off guard with this growth spurt, as she recently decided she doesn't want to nurse, so I think my body wasn't "forwarned" about the spurt coming on.

 

I drank some beer last night, a ton of water, had fenugreek and am adding in an extra pumping session today. Also, I am pumping for 5 mins longer than usual (after their all dried up to try and sumulate a growth spurt)

 

Can I do anything else?! If you EP, how on earth do the boobs "communicate" with the baby to know the baby needs additional calories?!?
