Not producing enough milk....

Janna
So im 5wks pp. I've been trying to exclusively breastfeed but haven't felt like I'm producing enough milk. I'm constantly feeding her almost every hr and a half and this week she's no longer sleeping for 3-4hrs straight at night. *really miss those days* I decided to try powering pumping to produce more milk but barely get 3 oz between both sides which took almost an hour to produce. Have anyone tried power pumping (ex: pump for 20mins, rest for 10, pump for 10, rest then pump 1 more time) and started to produce more? How long long before you saw results and how many times a day? Also, have anyone tried lactation cookies or mother's milk tea? Thanks!
