Hi there. I have a three week old newborn. BF is going well and her weight gain is good. I think I have an OS issue on the left side (it's twice the size as my right breast and DD chokes on the left) so I am starting block feeding for three feeds (I know you're supposed to do it by hours but she only eats every three hours during the day and that's because I wake her). I am going back to work in three weeks-ish and am planning to introduce the bottle and start pumping at week 4. My question is when and how long to pump? Before nursing? After? What about my mega boob? I def don't want to make that worse. I will be working eight hour shifts overnight and in the evening. How much EBM should DD take during a feeding and how much should I leave DH with? Thank you. These forums are very helpful!
