My son was born Monday at 25 weeks. I've been pumping since 4 hours after my c-section. Tonight at my 8pm pumping I was able to get 3/4 of an ounce total. That is the most I have had. I just pumped again at 10:15 and only got a drop. Is this normal or is something wrong? Bringing him breast milk is the only thing I can do for him so I am panicking thinking I am losing my supply.
