Help !

So this is long I apologize but I need some advice. My son was in the nicu for a month and he is now 6 weeks old and we are at home. I am exclusively pumping. He eats every 2-4 hours all through the day and night. I pump when he eats so anywhere from 6-8 times a day. At what point should I try to get my baby on a schedule and how do I do it ? I see where other moms say they drop a pump at night and that's something I dream of ! He eats anywhere from 24-32 oz of milk a day and I produce about 34 oz a day, but have a huge stockpile from when he was in the nicu. I don't want my supply to go down if I drop a pump when he is on a schedule. Please help !
