BF around 9 months

iluvmylab

Are BF babies still drinking about the same amount of milk around 9 months?  I'm a teacher and plan to BF for at least a year.  They are working on our schedules now and might be able to give me the same set up I have now which allows me time to pump twice without having to ask anyone to cover my class.  Right now, he drinks about 15 ounces at DC.  Will this most likely be about the same even though he'll be eating solids?  Or will it be a little less?  Basically trying to figure out of I could manage with one pumping session at work next school year or not.
