I am going back to work soon, and want to start working on my freezer stash. I've read that it is best to pump right after nursing to boost supply. My concern is this. My daughter usually nurses one side at a time, so if I pump both sides after nursing, will there be enough milk in the opposite breast in 2 hours for her next feeding? I'm worried she won't get enough milk. How long does it take for your body to produce the 2-3 oz that you've pumped out?
