Re: Going back to work - begin pumping & bottles now?
In my experience, we tried a bottle out about 3 weeks or so before I returned to work with DS1, and it was about 1 week ?? before I returned to work with DS2. I pumped a lot ahead of time for DS1 - we never had an issue with lack of stash, actually ended up throwing some away . With DS2, I only pumped enough for the first day (way stressful, I don't suggest that!), and have not had an issue with enough milk. I also did not pump anymore than I absolutely had to for the first day, and DS2 never got a bottle after the initial trial until I went back to work. I despise pumping (I did it for a year before, and will do so as long as I need to this time), so I avoid it if at all possible.
My thoughts would be that if your DD has taken a bottle well, and is back to EBF, this shouldn't be a hurdle for you. Start pumping when you return to work since you have a stash. With an OS issue, I woudl avoid pumping when it isn't needed.
Hope that helps!
