Am I pumping enough?

Lauren • Had my sweet girl 02/22/20 - 5 weeks early due to rare genetic disorder💗 Had my handsome man 09/30/22 - 3 weeks early due to low birth weight💙

My daughter has been in the NICU 2 weeks so I don’t breastfeed I can only pump for her. I was trying to get my supply up at first so the nurse told me to pump every 2 hours for 20 mins. My supply has gone up significantly so my question is, do I still pump this frequently?

I feel bad when I’m busy and I don’t end up pumping for another 3-4 hours. It makes me feel like I’ll fall behind on my supply.
