why don't you try pumping every 2 hour first? there is no magic formula to have more milk.
what i recommend is that drinking 1 cup of water BEFORE and AFTER pumping at least 15 mins each side. but you need to keep doing this for a week to notice the effect. you can also take supplements and drink herbal tea...lastly have TRUST in yourself that you can 100% breast feed the baby...looking for short cuts and lazy will not work...
