Yes! :) I pumped after about a week trying to breastfeed (my son was a VERY aggressive eater, and couldn't get food fast enough so I pumped and bottle fed so he'd be more relaxed) And I pumped for about 3 weeks exclusively, by 2 weeks past delivery I was prepreg. size, and a few lbs under. But you should also know sometimes if you strictly pump your milk supply can dry up unexpectedly. I was pumping a LOT a day, like 4+ozs every 1-2 hours I woke up one morning to go pump and I was completely dried up. I'll be strictly BF'ing this time, unless we have to go out somewhere for a while, then I'll pump.
