When I pump I get 99.9% of what I'll have at the end of my 20 min session during the first 5-7 minutes. I keep the pump on for the 20 minutes because I'm new to pumping and I figure that it will help increase my supply(that could be hogwash....?). My question is, am I just getting foremilk now, or is this it? Do I just get it all out in the first 5-7 min and the rest is just trickles...? When J eats off of my breast he eats for a long LONG time still (at 6 weeks he eats for about 40 min total, 20 min on each breast) but I know he's still getting milk for that long.

Am I doing something wrong? Is this normal?
