My LO is almost 7 weeks old. I just went back to work and started pumping. Right now I don't have much of a stock pile in the freezer maybe 1216 oz. I just found out next week I'll be flying out of state for a job interview. I'll be gone from LO about 30 hours total. I can pump enough extra between now and then but I'm worried about traveling, having to be on an interview and having to pump. Any words of advice? How to store/handle what I do pump while I'm gone, traveling with a pump and fresh milk, etc. I'm not sure how I'm going to do it all and survive that much time away from LO.
