Just be aware that that natural amount may disappear over time or if you decide to spread out the daytime sessions, but it will sure save some money if they will take it; my older baby refuses it now and says it is yucky. I was pumping like 70 oz a day at one point. Filled the freezer to use when I decide to quit and cut back on purpose, and now I make exactly what we need per day. I just needed my life back to some degree instead of pumping all day.
