Increase milk supply?

Hi moms, does anyone have any good tips for increasing your milk supply??

Power pumping is great, you essentially pump 20 minutes, rest 10 minutes, pump 10, rest 10, pump 10. There are some foods like oats that are meant to help but I never really know whether to believe that. Good luck with increasing the milk!

Once I eat alot and drink plenty fluid, my breast is full.
