i just want to repost this for everyone. it worked wonders for me so i hope it helps you all too.
if you need to fatten up your milk and keep up/increase your supply, make sure to massage your breast while you pump. rub toward the nipple from every direction. it will help to empty your breast more completely and signal to your body that you need more milk. i usually get atleast a second letdown. it takes longer, but it's because your getting out more milk and getting that second letdown. hope this helps! oh and i EP
Re: Increasing/maintaining supply
I have had TONS of success with this. Also, you can jsut restart your pump if you don't have the button. I can get another ounce at least if I hit the button!
