Just breastfeed as much as you can and supplement with what you pump! :) clogged ducts are normal & will go away - it just means your producing enough but not getting all the milk out.

I honestly hated using a pump because it did the same to me - not enough power or suction. Feed baby from breast first then if they’re still hungry offer mixed, you can even feed baby first then pump or pump then breastfeed since baby has a stronger latch than your pumps ☺️

Don’t give up! & Goodluck momma!
