I go back to work five weeks as of Monday. My daughter will be 7 weeks old at that point. When should I start pumping? I can't remember what I did with my other baby. I want to have a stash saved before I start work because I don't think I'll be able to pump at work (I'm planning to pump before and after morning and night feedings - and pump on the weekends). Anyway, I don't want to start pumping too early and mess with my supply, but I want to pump soon enough so that I have some frozen milk ahead of time. Any ideas from you wonderful Mommas?
