I think that's right on target joes.mom. I feel like if I needed to, I could get however much milk I wanted. I only pumped twice yesterday and pumped until I thought everything was really empty, and brought home about 12 ounces. Trixie ate about 5, so when she does start eating more (soon, I hope!), I can add that third session or pump longer. I didn't try for a second let down in the morning.
The funny thing yesterday was that I got agitated and anxious in the morning between the first time I pumped and the second time. I felt two letdowns before 1 pm and I got more and more anxious until I pumped. It was weird. I hope it doesn't happen today. And then I was pretty engorged when I got home and overnight as well, but baby is reverse cycling a bit so this morning all is well.
