I've been both breast feeding and supplmenting with formula, but sometimes I didn't have baby nurse before giving her a bottle, but i would still pump at some point..well last night and today my boobs have been so soft and just feel empty. the day before though I pumped so much milk...apparently all it takes is 1 day for your supply to just go way down?! agh! really didn't know breastfeeding would be such a science.
hopefully my supply goes back up if I pump a lot more frequently and strictly nurse before a bottle.
