How much to pump over night

Jazmine • FTM to Summit Rae

I just returned to work and my 12 wk old baby sleeps overnight. I pump 2-3x a night. I produce 3-4 oz total in one session. I was wondering in your experience could I just go to one pump a night or would that affect my supply and start losing it? Or have u had an ok experience with just one pump?
