I am freaking out about not having enough milk for my ds. He will be 10 weeks old when I have to go back to work Nov 5. I am a nurse working 3 12 hour shifts a week in a very busy ICU. With travel time etc, I am usually gone from 5:45 am to 8:00pm. With my 2 year old dd, I worked night shift. DH usually only gave her one bottle of EBM while I was gone, so I had no problems keeping up with her demand. She slept through the night at a very early age, even exclusively bf'ing - and she is still nursing now. But now I am working dayshift, and I don't know how I am going to be able to pump enough. My goal is to consistently pump 3 times while away. But I know that won't be enough. Any suggestions to make sure I can keep this baby only on breast milk?
