Trying to increase supply

Elizabeth

Hello ladies. I have been brewstfeeding my little one for 3 months now. I feel I am rynning out of my freezer stash (only use that when I'm at work). How can I increase my production? I feel she eats more than I can produce. I'm power pumping once a day (started yesterday and plan to do it for a week) and I am starting to pump after every feed. What else can I do? I really do not want to have to supplement. Thanks!
