Re: Away 4 times / wk for 3 hour stretches - need to pump?
i agree with PP, plus i'd say, it probably will be easier and better for your supply if you do it at the SAME time every day. that way baby & dad will have a routine, and your body will know when to produce more milk (when you're going to pump) and when not to (when you're away). honestly, depending on the baby's age, even if you nursed right before you left, and nursed right when you got home, 3 hours might be ok without that bottle in there. leaving a bottle is nice for baby & dad, of course, but you might find as baby gets older it's less necessary.
write write write!! i did the same thing (though baby napped on my chest while i wrote for 2-3 hours every afternoon).
