Thanks setof3, that is very helpful to know.
That is kind of what I am doing - atm I am going anywhere from 3 to 4 hours but aiming for 3 1/2. usually if it's 4 hours it's because something has held me up! It's very hard when we have to go somewhere at a certain time, I end up adjusting my pumping times to fit in... I have to go out at 12, so I'll pump at 11:30, then I work backwards from there.

Had 6 week check yesterday... even though Arlea is not drinking to her 'quota' she has gained 600g in 2 weeks (although that was clothed so take a bit off, still a good gain )
