Very important point below!

Anne Rogers wrote and I snipped:

over the next 3 days I'm going to try pumping after feeds to
increase supply

but do not give your baby the milk at that point! Store it, and use it
only when you believe you need to supplement (or sometime much later
down the road when you are separated from your baby). The idea behind
pumping to increase supply is that you are taking more milk from your
breasts, thus demanding more, and your body responds by producing more
in the future. If you turn around and feed this milk to your baby right
away, he will not demand as much the next time he nurses, and you're
thereby actually damaging your supply, not increasing it.
