Homeschooling with a Newborn

Lately I've realized that I am in denial about what school (and everything else) will be like around here when number four comes.  I imagine us peacefully having school while I nurse the baby.  I think I need to be more realistic and allow myself a month or two of doing nothing or just the bare minimum as far as school goes.  I guess this is one of those things where I wont know how it will be until I'm experiencing it.  Does anyone have any multitasking tips as far as homeschooling with a newborn???
