Drink lots of Hot Chocolate or Teas & the heat helps to produce more milk 😉 thank me later lol it actually works.

Believe it or not, the hops in beer will boost your supply too. I sometimes would drink a beer right after a feeding and my milk would be full again by the next feeding.
I always drink lots of water daily but still needed to resort to other methods at times when she wanted to comfort nurse.

Water, water, a balanced diet, and feed on demand.

I hear brewers yeast in things helps. I never ate anything specific to increase my supply but brewers yeast is what my friend suggested to me. :)

Blue Gatorade 😂 idk if it's an actual thing, but it works for me.

Drink water! Coconut water or Gatorade too. I also make lactation cookies that I’ll make and eat them everyday.

Hand express your milk every couple hours for about 5 minutes for the first few days it helps a lot. They said it’s helps you produce a lot more milk

Anything with rolled oats. Oatmeal or oatmeal cream pies.
