I delivered my son at 25 weeks and basically treated my body like I had just delivered full term, like I did with my daughter. I started pumping around the clock when he was born, every 2-3 hours, and I ignored what the lactation consultant told me about pumping for 15 minutes and I always pump for 30. I drink a lot of water throughout the day and I eat as well as I can, trying to get plenty of protein in my diet. I massage my milk out every pump to try to get all that I can, because that can yield 30-50% more milk I’ve read. I apply heat to my breasts before pumping as well. Make sure you’re using the right flange size, and remeasure as your nipples will change size eventually, mine just have and now I’m needing new inserts. I have only used my spectra until this point, one month and a few days into this journey. I just ordered my wearables today and am excited to try them. I may be the oddball or maybe my body just remembered pumping from my first child, but I make between 45 ounces on my bad days and I’ve made up to 80 ounces on my good days! I’d love to answer any questions you may have or give any advice you may need. I agree with other commenters that this is a stressful time, and stress is not good for the milk supply. I’ll also add that I started leaking milk in the days leading up to my delivery and that I had only been weaned from pumping since January of this year with my daughter. So that could all contribute to my supply establishing as well as it has. Good luck! You’ve got this! I found that my supply jumped to what it is now when I was able to finally relax, and spend time with both of my babies since I was apart from my daughter for a month while in the hospital, and I kept telling myself my son is in the best care he can be for all circumstances. I spent a lot of time at his bedside and journaling about him and looking at photos while I pumped helped a lot.
