I gave birth to my son a whole month early but my milk thankfully came in the second day and I was pumping about 10oz maybe more a day then when I got home I was still pumping good but when my baby got home everything went down hill I would feed him and pump and then they put him on formula and breast milk so now it's hard to pump like I should because I sleep. He keeps me up all night so I literally get no sleep at all anything that can help my milk come in better I'm now only getting 1-2oz when I pump now and I need milk for my little man I don't believe in formula and he only has to be on this formula for a month so I would love any kind of advice to get my milk back what I can eat drink pumping methods? Please help
