I'm a FTM exclusively breast feeding but want to start pumping to get w supply stocked up for when I work or need a sitter. My LO is 3 weeks, how do you pump enough to store and still have enough to feed? Is that a weird worry I'm having? Also WHEN do you pump? She's currently eating every 2-4 hours just depends on the day. I've tried pumping 2 hrs after I feed her, and I'm getting about 2oz per side on a good day!
