Re: increase supply through pumping?
You can always increase supply. Add in more nursing sessions and more pump sessions, and you should see an increase. Be prepared to be patient and persistent- pumping will not bring your supply back in a single day or even a week. You're looking to produce just slightly more every day- you're being successful if even if all you get is a few drops more than the day before.
