Re: increase supply for pumping?
Well, when I had to briefly pump when ds1 was 5 days old (cracked, bleeding nipples - eek!), I was told to pump every 3 hours around the clock, 15 minutes per session. So yeah, I think once per night is not enough.
Also, make sure you stay hydrated (lots of water!), eat oatmeal (helps boost your supply). You are doing great Alli!!!
