I would drop it to 3 hours and if it drastically affected my supply I went back to 2 hrs. By
the time he was 9 months I was
pumping every 4 and had a ton saved in
the freezer. My son was preemie so I pumped right from the moment he was born. They let me put him to Breast a couple times but that was until he was a couple weeks old so I had been pumping my milk for him til then. He never latched after the one time so I exclusively pumped for a year.
