Skipping a night pump?

Amy

I saw someone posted a 3 hourly pump schedule for newborn to 3m. I’m wondering if anyone’s skipped the 3am pump regularly without major issues. Will that really decrease my supply to go 6 hours without pumping? I have a 3 year old so I can’t ever catch up on missing sleep, I’m lucky if I get 4 hours a night right now. My baby is 2 weeks and I breastfed my first so I’m pretty new to EPing.
