Tips or products to increase milk flow?

My LO is EBF. Lately, he’s been feeding from both my breasts each feeding instead of the usual just one. When I pump at night, it’s a lot lower than it used to be. I’m curious on what other mama’s on here have done to get or keep their milk flow high.

I’m trying to pump more often after feedings. (It’s difficult because he gets hungry at random times. Sometimes 1 hour, sometimes 4)

I also take Upspring lactation supplement drink mix at night which helps. I’m going to start taking it in the middle of the day too.

What do y’all do?
