My son was born at 27 weeks. I have planned on breastfeeding. Due to coming so early, I'm having to pump rather than nurse. During the day I'm keeping up well with the every 2-3 hour schedule. I'm either in my room or at the hospital with him most times. But I'm having difficulty getting up every couple hours at night to pump and I'm noticing I'm getting less when I do pump. Any suggestions on night time pumping? I set alarms but sometimes I don't hear them. I really don't want my supply to dry up because I haven't been waking up.
