Hi all, I have a pumping question.... I've been pumping after my son feeds to start building up a supply. I'm only getting maybe 1/2 an ounce to 1 ounce each time I pump or less. I am going to start pumping when he's out cold sleeping if it's pushing the 3 hour mark, but when is it best to pump? Right after he feeds or wait a little bit? I am worried to wait much longer after he feeds incase he gets hungry again! Thanks!
