So I need some help or reassurance. my daughter is going on 6 months old (3 months preemie). I pumped the first 2 months due to her being in the NICU. my supply has been great and I've been able to keep up with her no problem. I have probably over 600 ounces in the freezer. well my menstrual just started and my supply took a huge hit. she seems to be getting enough to eat but I'm barely able to collect/pump over an ounce. has anyone gone through this or have some advice to get my back up?
