BF/pumping schedule help

Kaitlyn

I’ve been able to pump 3-6oz each time at a week pp. I’m still confused when is best to pump. Since we had some latching/jaundice issues the pediatrician said to BF for up to 20 minutes, offer 2oz of pumped milk (or formula if I didn’t have enough) and then for me to pump 15 minutes every three hours. I am already getting extra milk to save in the fridge. I dont know how long I should keep doing this. Any suggestions? Pumping every 3 hours is getting to me a little.
